The Hardest Math

[@Allstuffthatfascinates]

in my student life, the hardest math actually had hidden hints which led to easy solutions. just that hints were hidden.

[@vaimast2825]

Hi thats arcane difficulty right?

[@davidk7212]

The hardest part for me was becoming comfortable with using the freedom and creativity necessary for writing your own proofs.

[@rtothec1234]

Reconstructing Euclid’s geometric proofs from _The Elements_ with freshly sharpened pencil, compass and straightedge is pretty fun if you are a young.

[@larryyonce]

Proofs are often hard to follow and understand, and, of course, difficult to write yourself. But definitely rewarding when you "get it." So satisfying. A+ video sorcerer.

[@TheMathSorcerer]

Absolutely!

[@21ruevictorhugo]

I started my studies in mathematics by taking a group theory course. Yeah, crazy, huh? It was the only class that met late in the day and I was working full time and I could get to the class after work. I loved it immediately. Learning symbolic logic, set theory, all of that, was to me like the most fascinating thing I had ever come across in my life. Difficult, yeah, but a complete joy to think about something for days and days and then suddenly have the Ahah! moment. I still have the Herstein book from that course. I went in to topology and absolutely loved that as well. By this time I was doing directed study because there weren’t a whole,p lot of students interested in taking these courses. And here’s the thing - I find calculus so much harder than abstract algebra! But I force myself to do problems every morning just to keep my brain sharp. (I’m 78).

That is awesome!

[@jamesmclean5790]

Before I took a class on on writing proofs, I took a class specifically on logic. I feel that proofs benefitted immensely due to that decision. I loved both classes, but where I excelled in writing proofs was in Abstract Algebra and Real Analysis. It was there I learned more than ever how careful organization is an absolute necessity. I took care to make a Word document with all the definitions as they were introduced and a separate doc containing each theorem, corollary, lemma, etc. in their chronological order. Then when presented with a proof, I would copy and paste only those parts of the documents that were relevant to the task. With less clutter, it was easier to organize a plan of proof. And knowing that the odds of everything needed to write a proper proof was right there helped focus. This is how I got past these classes successfully. As a math tutor, this skill has helped me develop more insightful approaches to any given problem students encounter. A good tutor must not only know how to solve a problem: he must be able to apply logic in such a way as-to break it down to elementary terms for most students. Proofs open one’s mind to this type of thinking. I’ll cherish it for as long as I am capable.

[@johncoleman2990]

I like your approach and organization of the subject.

[@mmilrl5768]

I'm taking discrete mathematics next semester and I'm looking forward to it. My friend told me it's the hardest math class he's taken but he actually really enjoyed it. I know it's entry level proofs, but I wouldn't mind taking more advanced proof based math courses in the future!

[@nikolasmakiyavichi5928]

In computer science classes, before algorithm analysis i took a class on proof writing and it helped so much!

[@icybrain8943]

I like to think of it this way: solving equations in computational math classes is proof writing with a really narrow scope and tons of supporting assumptions given to you for free. Venturing into proof-based math is learning to widen that scope and remove things given to you for free by building things from scratch yourself.

[@jacobharris5894]

Kind of like making a game in Unity or Unreal engine vs making the game engine yourself.

[@peterzeman2749]

I did my PhD at Charles University in Prague, now I am a postdoc. It is interesting that our curriculum was kind of different from the one in USA. In particular, our first year at university everything was already with proofs. The first year involved analysis (1 and 2), linear algebra (1 and 2), discrete mathematics and everything with proofs. So we were really forced to learn how to write proofs in the first year and it was very tough in the beginning, but it paid off. Also during the high school the university organized a distance seminar in mathematics for high school students. The organizers would send out (not only) olympiad-style problems, but we would have roughly one or two months to solve one set of problems, so it was less stressful and one could think about it at home for a long time. This was basically about writing proofs. Also, some problem sets had accompanying text which would introduce a university-level topic (group theory, graph theory, probability, combinatorial geometry, etc).

[@TheMathSorcerer]

Oh wow so cool, thanks for sharing 🔥

[@CEOofH-np6tl]

I feel so much better after watching this. I’ve never taken an advanced mathematics course, but I have taken introduction to logic. (The proofs made this class feel impossible). After learning how to properly cite (the hardest part about logical proofs in my opinion) I felt pretty accomplished.

[@stevescodinglab]

Thank you so much for the Book of Proof recommendation; just downloaded it!. And great video as well 👍

[@ariuwu1234]

I once told a teacher in my high school I wanted to study theoretical mathematics at a university, to which she responded with something along the lines of "I had a student, she was interested in mathematics, she went to uni and gave up. You will hate proofs, you will come back in a year and tell me exactly what she had told me." So, me being me, I said to her "Thats exactly why I want to study mathematics, I want to learn about proofs and theoretical, abstract mathematics. In fact I can promise I will come back to you in not one but six years to show my degree." At that moment i felt pride. I was so pride I stuck with my choice and what i love. Right now im selfstudying beginning abstract mathematics and in two months I start my first year of uni. Even if I don't like it, i think abstract mathematics is one of the most beautiful things in the universe and I am proud of myself for at least trying. I wish myself luck and happiness, as well as to other people who want to learn more mathematics. I may do an update in some time Edit: I also forgot to mention that after reading the first few chapters of Book of Proof it changed how i view the world, how i look at arguments of other people, i can more easily identify flaws in logic, and i think thats very beautiful.

[@calebscottalons]

I've been seeing a lot of comments that talk about getting over the creativity hurdle. Proof-writing really started opening up to my mind when I finally got over the psychological milestone of believing that I did, in fact, have the creative capacity to devise my own solutions to new problems. Receiving my first nonzero score on the Putnam at university was another contributing step, and over the next year I practiced and had gained more confidence. I did end up scoring again the following year, and I hope to score again this year.

[@sirlukelimbo2044]

I quite agree with everything you have said. Proof writing is really hard to learn (and would also hard to teach). Writing proofs consider a dense amount of knowledge imo. It considers the way one understand the statement, what statements have been proven already, what’s obvious or needs to be shown first. By Van Hiele’s paper, rigor is the highest level of math knowledge. Despite of all of these struggles, it’s very fulfilling to write proofs that are correct and clear, at least for me. Taking a pure math course change the way one thinks and reasons.

[@avernvrey7422]

Nah, so far, listening to negative reviews has never been a mistake for me. Helped a lot.

[@bigbluebuttonman1137]

"Try to apply that careful thinking to your life situations." Believe it or not, this is good advice. Obviously, don't start throwing QEDs around in conversations with the chef, they're probably not gonna know or care, but I remember trying to employ this careful approach to problem-solving with things outside of math specifically and it was very helpful. The logical thinking process, anyway.

[@badatdoingmath]

“How to prove it” and “A transition to Advanced Mathematics” are my favorite. Even a dumb dumb like me was able to get through them both during undergrad. 15 years later, and they are the few books I made sure to keep when moving from place to place.

[@freepointsgals609]

Honestly for me, my introduction to proofs class was when I fully fell in love with my major. Don't get me wrong, I'm not great at it, but despite the difficulty and even perhaps because of it, I can't see myself doing anything else. That class was kind of like true love's punch in the mouth. Side note: I taught myself Boolean Algebra after learning to write proofs, and it was comically easy for me after being introduced to basic set theory.

[@suckmyartauds]

This is so true. I did terrible in intro to proofs and barely understood it but I still love it.

[@Josiah-ve6su]

I took a proofs course and we used Hammack's Book of Proof. It's a great book with great explanations and exercises. It was a really challenging course but now I see those skills have been indispensable for all the math I've done since.

I'm so happy with what you're doing!! I follow you frequently especially in the times I have challenging learning goals to achieve. I'm A software Engineer, Functional programmer, distributed Software architect, but my first passion is Physics that I studied at university before my engineering studies first in electronics and Automation and then moved to Software Engineering field in which I've been working for years now in my US company. At secondary school I was not showing too much interest in mathematics, I was seing them not concrete and not so difficult and It made me not give too much efforts in Mathematics. I was not assisting to Maths classes but at exams I was always above the average. I was and I I'm still very passionated by Physics And was passing all my time studying Physics. My love for mathematics came during my undergraduate Physics studies at university specially when I discover the speculative and abstract part of Quantum Physics, General relativity, particle physics that are parts of Physics deeply rooted in theoretical and abstract concepts but that have deeply impacted the science and the technology and our life. I started giving more efforts to Maths And I as a consequence having great Scores. Actually my next field of studies is going to be Artificial intelligence starting soon in a graduate study program leading to a Phd specially with a lot of mathematics. I'v been following you for months and I've finally decided to also go back to mathematics and study them. I I've already bought on Amazon the book. "Everything You Need to Ace Pre-Algebra and Algebra I in One Big Fat Notebook (Big Fat Notebooks) Kindle Edition" that you recommended recently It's a good book to go back in math. I read a lot, I pass my time studying, I love the struggle of learning difficult things and my brain like complex things and abstract. I should get to learn the proofs and move further. You inspire me so much. I hope I'll may be soon or in the coming months share my experience and my passion with your public. Thanks for what you do, for inspiring us so much! I love what you do and the way you do it with so much dedication and passion.

[@vikramkrishnan6414]

I got my Bachelor's in Engineering, and went to the US for my Masters. There my uni basically allowed us to take as many courses from any school as possible a semester so long as we hit 4 courses from the School of Engineering. We had to take 2 courses in a minor. I took a course and then another and then another. Soon I was taking 7 courses a semester, in math and Engineering combined. Real and functional analysis, topology, the works. Brought down my aggregate GPA, but I had an absolute blast. Not to mention, I became known as the weirdo who did 2 Masters degrees in STEM in 2 years and wrote a thesis and survived to tell the tale. Algebraic topology without a shadow of doubt was the hardest course I did. Analysis you basically go backward from conclusion to assumptions. Algebra is pretty straightforward. PDEs and ODEs are fun and very applied. Ditto for numerical stuff. But Hatcher broke me. I never got an intuition about what I was trying to do.

I just finished my first semester of Pure Math. I had a proofs course, which I passed. However, I did not get the results I wanted. I'd been feeling nervous for the continuity of my career, considering I will take Calculus I next semester, and after seeing some of the assignments of previous years' courses I thought, for a brief moment, I might not make it through. But I found your video just in time. Thank you for giving me the confidence boost I needed in order to keep studying proofs during vacation. For the course I used Ethan Bloch's "Proofs and Fundamentals" (great addition to your collection, if you do not already own it); I will continue with the exercises from "Book of Proof".

[@gopalparam6401]

Dear Math Sorcerer, I love this topic and your positive energy. I am in my mid-sixties and trying to learn some of these things. However, I do want to point out that there is a tremendous, by that I mean order of magnitude price difference between the same book that is sold in USA and third world countries like India. Yes! Mr. Jay Cummings book on proofs costs $ 18.35 + shipping in the USA, but in India it is nearly $68 + shipping. I can understand the higher shipping charge, but four times the price is daylight robbery. However, Mr. Jay Cummings' book on Real Analysis is reasonably priced in both countries. Pricing is such a puzzle!

[@dumbfrog123]

Schools in the US usually don't teach proofs until college, except for simple two-column concurrent proofs in high school geometry classes. That is why a lot of people feel overwhelmed when they first encounter proofs in college. I am learning proofs for fun and might teach them to my kids as well.

[@nomarxistspls90]

That's the same in the UK too. I'm a 2nd year math major and I taught myself how to write proofs at 16-17 because i knew i would need to be at least competent in them going foreword. It was crazy to see how many guys in first year had no exposure to basic proofs (direct, contrapositive, induction, etc)..

[@stevenlitvintchouk3131]

I learned a few special situations earlier in life. I had an introduction to symbolic logic when I was in 6th grade in elementary school, and I also learned proof by mathematical induction when I was in junior high school. But those are nothing like trying to do a proof in abstract algebra.

[@Science4Ever]

Hey Math Sorcerer, how about you come up with a proof writing series where you take randomly some problems from those books you just mentioned and break them down in a "explain like I'm five" manner so you can fill that hole on KZbin?

I firmly believe that none will ever truly master the art of proving stuff. Each time you have to prove some new, non-trivial result you kind of have to invent something. Sometimes chaining some known techniques/results in a clever way is sufficient, sometimes you have to come up with completely new observations and techniques. Proving stuff often requires CREATIVITY

I had a good professor for my sets and logic class, which was my introduction to proofs. It was very down-to-earth, I loved the class. Dude had the heir of “I would really like this proof to be an elegant 1 or 2 line- oh doh, it’s gonna take more, *sigh.*” (Maybe not exactly like this). He also liked talking about the history of math, which frankly, really helps make the field more alive. There’s a lot of interesting history, it makes these topics feel more alive. There’s a lot of intro to proofs books, but even an online lecture that’s engaging is really the sort of thing that I’d want to suggest.

[@cornucopiahouse4204]

I have always been "good" at math, from primary school to secondary school (British system), and I was never worried about not getting a good grade in math. When I entered college, I wanted to do theoretical physics. One semester in, I realized that my thinking is more of a mathematician than a physicist, so I switched major. I spent most of the time writing proofs, honing and honing along the way. End up hurting my GPA because I did not balance the theoretical side of math and the calculational side of math, which is crucial when taking courses. For students, do keep that aspect of doing math in mind also.

[@philippg6023]

It is the most difficult but also the most beautiful and important topic! And do not be afraid of basic topology. The beginning is not hard. The proofs are really straight foreward mostly really short and a little bit talented student can even do them by him/herself. Fun fact: there is a famous topology book without proofs, where ALL proofs are left as an exercise for the reader.

We need first to pass writing part where do problems and next week go to speaking part where we get theory questions and present them in front of teacher. This theory always includes motivation for studying topic, definitions, theorems, lemmas, but everything with proofs that we need to know. It is actualy necessary for passing subject. These proofs are always big deal for students and sometimes are really hard, some of them appears also on writing parts. But I am thankful because we are faced with them and now, in my third year I can figure out many proofs on my own, especialy in topology.

Imagine taking a basic undergraduate course in Geometry... to find out it is about how to build all the geometry from scratch, only with few axioms and no coordinates. Through functions like the metrics and Euclid axioms, reformulated by Hilbert, step by step, what is a point, a line, a plane (sets and sets...), an angle (using points, lines, distances), a triangle, isometries, equivalences,... polygons,... circles... painfully, proof by proof, given to you and asked to you as well. It seems one century ago it was the fashion to use exactly this course to train future Mathematicians in how to do rigorous Mathematics. Half a century later, it went off fashion and many places dropped geometry. They moved this proof training to Advanced Calculus (Analysis 1), and it is still the situation today in many countries (at least in Europe). How I can found a place where they still teach this thing? Well, some places have a very long tradition of not hurrying up because educational trends 😀

I’m sorry to ask this question, but I watched a video you posted two years ago and one of the two books you recommended people start with who want to learn math from Zero was “An Introduction to Abstract Mathematics.” There you say this is a great way to start (proof writing). Now you’re saying it is the hardest math to learn. I bought the book and it arrived today, and I’m already intimidated by the idea about relearning math (even if I was decent at it back in the day it’s been 15 years). I’m confused as to why if it is the “most difficult” type of math, why do you start someone off wanting to learn math with the absolute hardest?

This quote is force me to take seriously my math practice habits

[@elliottjustice73]

Do you have any suggestion for any online courses or material for Proof writing?

[@Bullshot40]

Makes me less confident having taken many classes....I now question everything and try to deduce everything logically before I jump to conclusions.....always using deductive reasoning and it drives my wife crazy....she always says, you have a reason for everything.....I literally don't know how else to do life anymore!

I feel like I i got really lucky in college with the professors I learned to write proofs from. I still struggled, and so did everyone else, but it never felt like the hurdle it seems to be for some folks.

The Cummings books are great . . . except for when it comes to answers and hints: there are barely any, which can be frustrating for self-study.

I am a slow learner. Math is hard. Here's the hardest subject.... the one you aren't trained in or practiced in or are supplied with tools for. With practice and time, you gain all those things. So I left off one part in another video comment... is the hesitation that comes from painful results of doing bad at first and from fear of failure. Not just laziness, but from a painful experience. Time to do a come-back round like you used to see in 1980's martial arts movies. Where the underdog gets training to strengthen their weak points and learn those basics. The hardest course, is always the one you are least familiar with in techniques. Don't let doubt keep you from getting back in there and training.

Could you do a video on a level mathematics and a level further mathematics and books a highschool dropout in the UK could use to finish A levels I've seen your GED video but Britain doesn't allow Ged

To know, proof theory is a part of mathematical logic? What are the steps(from the beginning) to study the proof theory? I’m interested. Thank you.

Hello, my favourite math wizard. How useful would it be for me to learn proof writing in my first year of Electrical Engineering? (In my free time)

[@guruvachansingh2864]

Please make a vedio on Compatible System of First Order Partial Differential Equations

[@travisjacobson2334]

OMG! I’m friends with Jay Cummings! He teaches at the University that’s about 10 minutes from my home!

[@wobbinhood1453]

man i'm doing an electric engineer undergrad and my calculus from 1 through multivariate have been more on the real analysis side because of an insane profesor, but goddamn i'm fucked by hating and sucking at the computation stuff i wanna say i have an incredible knack for proofing because i'm very logical but more on the declarative side of things and not so much algebraically where you need to be very organized and learn all the implicit algorithms to solve a problem it's been a weird 2 semesters and i kinda get the feeling i'd have a much better time with a math degree but i also just want to do robotics not academia

[@billylee5624]

Yeah I'll be honest, get your numbers out of the way. Jk, I know there's some quantifying that needs to be done. There's a certain set of words and rules of writing proofs that teachers want to see, and sometimes you fall short of that complete proof cause you reused certain words too much or something didn't make sense to the teacher. I'm so glad I don't have to take a course in Real Analysis and am free to make mistakes I guess, cause I got a C in introduction to proofs. Makes me glad I did my grad in Economics, while you do see set theory used in things like Microeconomics, when you take tests, you're not expected to write complete proofs or write out sets depending on the problem, generally, you just have to understand how to derive the formulas, part of which is in functional form like U(x,y) = (x^p + y^p)^p that has to include the Utility function which is indirectly differentiable itself if the utility is the constraint when taking the Lagrange to 0. Which is just complicated algebra as we do in optimization problems. Same thing with econometrics, but in the homework we are asked how key equations we use is derived given so and so equation so we can understand where it comes from. Which is not the same as writing a complete proof. Deriving is only part of that equation to writing proofs.

[@sophiabrown8573]

Sometimes I am unable to make out if I have crammed up a proof or I can contruct it myself. I don't intend to cram it but it gets stuck.

[@Roshawn-c2s]

The hardest math is Math word problems basic to advanced Or complex math word problems with real life practical application using all operations symbols or signs at once . Plus proof writing mathematical logic ! That's true too ! Sometimes or according to the statistics people had a hard time with math problems numbers and words like solving a riddle A key to advancing world whatever are disciplines are in science and mathematical fields. Myself Had a hard with math word problems , thats why I like math in a applied way, and still working at it, strive better at it on my own pace great comment what's hardest math Thank you

As soon as I clicked the link I thought Two words: Algebraic Topology- and Bingo great minds think alike

[@hikashia.halfiah3582]

I think that quote by von Neumann somehow often misunderstood even among mathematicians. It's actually quite hopeful quote instead of a hopeless cynical one.

[@aidan34i56]

Hey Math Sorcerer! Right now I’m going back to the very basics of Algebra I (For reference, I’m just learning why we solve for the value of X and what it represents). Do you think within a year its a stretch to say that I can manage my way up to Pre-Calc? I want to learn it before I commence my studies as a mature student come Fall of 2024. My first year will require introductory calculus and discrete mathematics.
