Introduction to Logarithms (2 of 2: Numerical examples)

Well... my teacher, here in Brazil, refused to teach us Logarithms because "it was too hard to learn" (that's how it works here). So, I decided to learn on my own and I found this brilliant teacher. Thank you so much for this, this is so important for people like me who has to find alternatives to this system that doesn't care if we learn (even the basics) or not.

[@randomviewer1285]

How do ur exams work? Do they just remove logarithms from it

[@BurningGreyX]

@@randomviewer1285 yeah, I guess so. I'm from BR as well, and only now I'm learning functions and logarithms on my own, even though I finished school in 2016. The public education is a joke, I'm glad there are videos like this on YT for ppl like me because I need to know this stuff for my engineer course.

[@takodachi7625]

@@BurningGreyX I'm brazilian as well, we have log on exams like ENEM (high school national exam) and college entrances but even studying in a particular school we don't get this explained really well here. my teacher is good but she doesn't have the time necessary to explain something in a good way, it feels rushed and sometimes we really can't understand it. I'm in my last year in high school and I also came looking for classes like this to try and learn these stuff on my own

[@lucastomaz977]

Actually, here in Brazil, we do learn Log, the problem is if u are in a public or private school, because the public teaching is far worse than the private. But, if u are in a private, u don’t learn if u don’t want to. Ps: For the “Big foot” the Brazil never got close to be a socialist country, so stop spreading fake news. Ps2: srry for my English 🙃

Please keep on uploading your inspiring lectures for future generations to learn from your talented insights. Best Regards, Alaa I. Ismail

[@obgprasa]

Excellent teacher. We did log to base 10 in our math, but now after 54 years, I am understanding what it truly meant.👍

[@leonelfederico245]

🤣Funny, I just learned it today and I'm 55. Glad to see others my age and higher still working to understand maths. This guy ROCKS!!!!!

[@pinklady7184]

You have a very quiet classroom and no interruptions from unruly students.

[@lolvirtue]

It's rude to interrupt when g o d is speaking

[@infinitesimotel]

He involves the class, it is a two way interaction. The wrong way to do it namely my experience with maths, is to sit there while the teacher yawns out a load of lines at you and you copy it down like a machine. He does not give the chance for students to idle because they are all participating in it together. This is a template example of the way a class should happen and one that is a perfect example thereof.

[@MsJavaWolf]

@@infinitesimotel That teaching style is pretty outdated imo. It had value when we didn't have the internet, information was valuable. Now information for basic topics is everywhere, the whole value in school is personal interaction.

[@R3_dacted0]

That's usually how all my classes are. Even after the teacher asks a question, no one says anything.

[@jursamaj]

@@MsJavaWolf It's true, you can learn a lot on the 'net. And the 1st thing everybody ought to learn is to be skeptical of everything they "learn" on the 'net. Also cream bun pointed out that Eddie's teaching style is *about* personal interaction, so I don't know what you're saying is outdated.

[@princywanjari]

so, due m personal issues, I skipped whole entire grade and so I could not learn what logarithms is, and this man explained in minutes. Thanks for doing it. This 5 year old video will help students even after years.

[@josh.chitrathomas]

Just came to this video because I couldn't understand how logarithms worked, my teacher said "that's just how it is don't ask how or why". After watching this video, it all made sense. Eddie Woo you are a legend!

[@ridaennasry6927]

explaining an idea in layman language reveals a deep understanding of the concept, as the saying goes "the only way to learn math is to understand it" you are a pretty solid manifestation of that saying, thank you.

[@darren141004]

these 2 parts of videos is what i learn 2 months in school... how i wish you are my teacher THANK YOU SO MUCH!!!

[@petroc62]

I wish I had a math professor like you in college. You take what in many cases are complex principles and make them easy to understand. I hope your students realize how very fortunate they are to learn mathematics from you. Keep up the great work Sir.

[@jenshub]

You can also say, how many time can you divide the result by the base until you get 1. So 3^4=81 and log3(81)=4 then 81/3=27 27/3=9 9/3=3 3/3=1 Four total steps so 4 is the answer. As for the log.sqrt3(27) you can first square the base and then work with 3 and then empower it So (sqrt3)^2=3 obviously and then divide 27 by 3 and then the answer by 3 and again so 27/3=9 9/3=3 3/3=1 So three times, 3^3, but 3 wasn’t the base. Rewrite 3 as in the base form (sqrt3)^2 and power that by your amount of steps (sqrt3^2)^3 that’ll be (sqrt3)^(2x3) or (sqrt3)^6 so answer is 6 Hope this will was clear enough and gave you another perspective on this :)

[@nwaneri0]

Would you say it's mentally more efficient to reason like this in order to obtain an answer?

[@LetsBeHuman]

I'm have Masters degree in CS. I need to brush up Math skills for Algorithmic interviews and this helped a lot. Your teaching is amazing and simple. Subscribed. Keep going sir. Please/ More videos please.

[@vinaykhandagale9635]

The best way to teach a class is to treat them all like they're morons. Love how he explains the simplest of things without assuming that something is general knowledge.

[@Superfantastictop10]

I remember try use logarithms at school...the explanation was if you want to get this number here, plug in this equation. I got the right answer by plugging in the algorithm, but learnt nothing as I didn't get what a log was. Great explanation.

[@yark618]

Super Fantastic Top 10 don’t worry it’s the same with all of us. I don’t think the teachers even knew

[@sharonjuniorchess]

I am coming back to the subject to help students but remember being taught how to use logarithmic tables to do calculations. The big advantage in the 16th century (when they were invented) was that you could convert multiplication problems into their log number add them together and then convert the answer back to denary. But there is another way where multiplication is made so easy that it is no more difficult than adding which is by using binary arithmetic which was what Liebniz used instead of logs. I think if we taught the history of maths students would get a greater understanding of how & why these things were developed. Logarithmic graphs enable one to see growth across a wide scale.

[@Angor6495]

i like your teaching style, and i think your students are lucky to get math explained by you, but i really feel bad that there´s no new knowledge for me on your channel. do you think you will someday make videos on higher mathematical topics (eg complex calculus)?

[@tojo4]

points at sqrt(3): "That looks gross" He's not wrong lol

[@oaklynnemberly8011]

that surprised me initially because my math teacher says similar things: "that makes me uncomfortable", "that's ugly", and such.

[@World_of_OSes]

The power function has two opposites; root and log, unlike add and multiply which both have one opposite each; minus and divide respectively. Because with power it matters which order they are in and with add and multiply it doesn't. 2+3 and 3+2 both equal 5, 2*3 and 3*2 both equal 6, but 2^3=8 and 3^2=9. So to undo 2+3=5 or 3+2=5 you would go 5−2=3 or 5−3=2. To undo 2*3=6 or 3*2=6 you would go 6/2=3 or 6/3=2. To undo 2^3=8 you would go 3root(8)=2 or log2(⁡8)=3. To undo 3^2=9 you would go 2root(9)=3 or log3(⁡9)=2.
