I used to hate math especially when it became more difficult during the end of elementary school and all throughout the rest of my public school education, I’m 29 years old and intentionally reviewing all of this information to be able to better teach my daughters when they reach this point. My eldest is homeschooled in second grade but I’m also facing my past and slowly loving math as a grown woman. I never thought I actually would understand it and enjoy it! I’m hopeful that my daughters won’t struggle the way I did! Please never get rid of this course! I’ll use it again for my eldest! 😂

I am 54 years old and I have managed to become successful but held a secret that I barely understood basic math. I have felt stupid, and so embarrassed for years that I just couldn’t understand basic math. I have learned so much today that I have long thought I would never understand. There are no stupid people. It is like I tell my sales team every day in regards to something new: when it comes to something we can’t, or don’t achieve, it comes down to two things: we either don’t understand it, or, we don’t care. Ty to the 1000,… power! Infinity Ty!

I received an associate in business back in 2018 and I just recently decided to go back for Environmental Science, which will need some math credits. I haven't really had to do much algebra in years so I totally forgot all the little rules such as going left to right during the order of operations. I do remember PEMDAS, but I incorrectly took it literally and did multiplication before division instead of whichever comes first left to right. I've watched about an hour a day for the past few days and all these little rules are helping me remember the basics so I don't end up lost when I have to take some of my upcoming math classes.

[@deloreshillcreative]

I am so much enjoying this course. I am on the order of operations. I finally understand it. PEMDAS, when I first memorized this - I did not understand the left to right in working the problem when it comes to multiply, division, addition and subtraction. I could never understand when I was in class when the teacher was teaching Algebra, and it was not explained fully the left to right. I remember thinking, that when I think the answer is one way, it is another answer. I was so confused and frustrated. Thanks to your tutorial I was able to understand this principal. At one time I hated math, but now I am beginning to love it. I will continue with the videos and learning. I feel like I want to go back to college. I am 81 years old and I feel this is a new beginning of understanding Math.

17:33 Expanded notation is writing the number in a long form by multiplying each digit by its place value. Expanded means long-form (for all the ESL folk out there). Notation is a word used in mathematics and it means how numbers are written. For example 10 is short notation. 1x10+0×1 is expanded notation. So 10 in expanded notation is 10+0.

[@Greenemath]

Great, good luck with your studies.

I am a 29-year-old man who graduated from high school and college. However, I never fully understood subjects like Algebra, Geometry, Pre Calculus, Calculus, or Statistics. Though I was not terrible at math, I used to forget formulas and make mistakes which made it difficult for me to solve problems. So, I have decided to go back and engage in some self-study to understand where I went wrong and how I can improve my skills. Thanks for the video. I think it was during my 9th and 10th grade years when things became increasingly challenging. In 9th grade, we only had substitute teachers and no regular teacher. In 10th and 11th grade, the professors appeared to be upset because most of us had difficulties in the class. Finally, in senior year, the entire class was conducted online.

I have some computer background and would like to learn Machine Learning as a career change. However, I am very poor in Maths and looking for a course which explains in detail from scratch. I have watched a few videos and most of them jumps directly into 'linear equation, exponential,...' which I stopped after a few since I don't get the concept. And I cannot take face-to-face courses due to family commitment. I am lucky that I found this video where I can learn all in one place (from high school to undergrad to graduate levels) while sitting at home. Thanks a lot Mr. Greene. You are a life saver.

[@Greenemath]

I'm glad to hear the lessons are helpful. The main thing is to do practice as you work through the lessons. You can use GreeneMath.com if you want free practice.

[@nyinyiandnyinyi]

Is it too much to ask if you could add chapters to your videos as your videos are very long (which is very very good and beneficial to those who have little knowledge in Maths). this way, it's easier to browse which part we want to revisit/focus. :)@@Greenemath

[@HYMN_SCIENCE]

For a few years my teacher taught me everything in this video but I did not learn anything... But this 15 hour video taught me better and know I understand it.. a feel like school is pointless

[@Greenemath]

School serves a purpose, although a motivated student can always learn things on their own.

[@HYMN_SCIENCE]

@@Greenemath yeah. Maybe.. but I think, the main problem with school is u can't pause and replay.. Btw the way, is the remainder of long division accurate??. Cause sometimes when I was practicing long decision I always check my answer on a calculator and sometimes the remainder is diff, daws dhat mean dhat it's inaccurate?? Or maybe I made a mistake in calculating?

[@Greenemath]

@Zaidmusic988 When you divide on a calculator it is using the decimal form of the answer. We will get to this during the decimal portion of the course, it's towards the end. Let's say you have something like 9/4. 9/4 = 2 R1 Since 2 * 4 + 1 = 8 + 1 = 9 In other words, you take 9 boxes and split them up into groups of 4 boxes, you will get 2 groups (4 * 2 = 8) with 1 leftover (8 + 1 = 9), this is the remainder. With a calculator, it is going to take the remainder and divide it by 4. 1/4 = 0.25 So the answer from a calculator would just be: 9/4 = 2.25

[@arielleshort2209]

I've not had a lot of support in math, so I'm having to learn from the bottom up at 33. Maybe in my lífe i can even make it to Calc 3. It's a dream, but one day I'll be good in math. These videos help me take the time I need to digest the materials at my own pace instead of being rushed in a classroom setting.

[@Greenemath]

You can make it as far as you would like. The main thing is to do lots of practice when you are at the basic level (Pre-Algebra and Algebra 1). This will make things a lot easier as you progress.

[@arielleshort2209]

@@Greenemath Thank you. I'm doing my best with it.

[@IvanMoscow-g7i]

@ 04:41 For everyone in the world except the USA, England and a few other "outsiders": The recognized reference system (from Latin) since the 15th century is the long scale system. The US and a few others, as usual, have to do everything differently. Reference: Million (10^6), Milliard (10^9), Billion (10^12), Billiard (10^15), etc. In the USA, all other steps are simply ignored and a completely new number system is used. The "short scale system".

[@Greenemath]

The metric system and using commas in the place of a decimal point is also a big difference.

[@Naoty_san]

[@Greenemath]

Most likely an instant download of math into your brain without the need for studying.

[@JartinVartinJlackwood]

It's so helpful to have everything you need to learn all in one place bc it helps you realise stuff you didn't even know you've forgotten by 24. No wonder I struggle with algebra when I can't even remember studying expanded notation! I'm starting a science degree at the open uni next year so this is a super helpful way to relearn maths beforehand

[@Greenemath]

I'm glad you found the course to be helpful, good luck!

[@caribbeanman3379]

I wish they taught us Math like this in school. In my school, they taught us the algorithm to use to get the answer. But we weren't taught the logic behind it. So it was all about memorizing steps with little or no understanding of the concepts of logic behind the steps. This is not a good way to learn. Understanding should have priority over memorizing. When you understand, memory comes easier because the steps are more meaningful. And even if you did forget some steps, because you understand the concepts, you can actually figure it out with logical deduction. But with no understanding of concepts, you're completely lost if you forget something.

[@Greenemath]

Understanding the concept behind a formula is key.

[@iggles1967]

Thank you so much for this! I’m an older stay at home mom homeschooling my son. I’ve forgotten what math I managed to learn in school. Was not my best subject. I’ve decided I need to review pre algebra and algebra so I can help my son. Thank you for this easy to understand course. ❤️

[@Greenemath]

You are so welcome!

[@slimshady4life689]

6:47:35 I really surprised myself that the only mistake I made was forgetting to keep the absolute value sign around 4+(-16) so I added -27 and 4 then -23+(-16) so I got -39. instead of adding 4+(-16) to get -12 converting it to its absolute value to then add -27+12 resulting in -15. The end result was -15/-3 = 5 instead of 9/-3=-3. small mistakes like forgetting absolute value and switching numbers from positive to negative and vice versa trip me up. i need to learn to slow down and recheck my work.

[@Greenemath]

That's a tricky problem with lots of steps. Going slower and checking each step is the key as you suggested. Good luck with your studies!

[@Maplesz]

I decided I finally want to understand math because I’m so tired of breaking down everytime I see a math equation I’m also extremely tired of barely passing math so I’ve made up my mind I want to at least pass with an 80 this year and I’m gonna try my absolute hardest to achieve that goal and I’m actually going to try to catch up to my classmates and stop making excuses like being in algebra 2 and having the same knowledge of an 3rd grader when you’re in 9th is embarrassing. So thank you so much for posting these courses 🙏🏾 gonna binge watch these and write lots of notes

[@Greenemath]

I'm glad you are motivated to learn math. The main thing is to work all the problems as I do them in the video. Don't worry about taking any notes, just work the problems. Good luck!

[@chrisalex001]

The problem with teaching students things like PEMDAS (in math) or FANBOYS (in English) is that they will remember the acronym itself and then mentally associate each letter with a meaning, a process that by definition they will have to carry out every time they want to remember. It is actually much easier, in the long run, to force them to remember the actual meaning from the beginning even if it is a lot to remember. Having a medium to help one remember is only functional if it is a whole thing, such as associating π (Pi) with an actual pie in order to visually remember that it represents the ratio of the circumference of a circle to its diameter. I can say from personal experience that PEMDAS has actually been at the very core of most of my difficulties in high school with higher level math (where it's all about the order of operations) precisely due to the exact same reason you just mentioned. Thank you for what you do!

[@Greenemath]

If you work enough problems, it should stick with you. There are lots of people that remember PEMDAS but then don't understand the MD and AS steps are worked left to right. It's a constant struggle as I get people commenting that "I am wrong" or "that isn't how it works". A simple check with an online calculator is all one needs to prove the result. Good luck and thanks for being a channel member.

[@chrisalex001]

@@Greenemath Yes, especially the fact that MD and AS work as one unit. So PEMDAS is truly more like P,E,MD,AS, where left to right establishes the priority of operation for MD and for AS.

[@Greenemath]

@chrisalex001 We definitely need a new way to say it but I'm sure that won't ever happen since this one is established.

[@carultch]

@@Greenemath I like GEMA: Groupings -> Exponents -> Multiplicative Operations -> Additive Operations. Groupings could be indicated several different ways, like division bars, brackets, function inputs, common superscript, etc, so groupings is more general than parentheses only. This also requires you to realize that division is ultimately a form of multiplication, and likewise that subtraction is ultimately a form of addition. There's still the underlying disputed order of operation issue, on whether implied multiplication by juxtaposition has priority over division. Middle school teachers, at least in the US, treat all multiplication the same regardless of notation, while professionals commonly give priority to juxtaposition. It certainly simplifies notation to give priority to juxtaposition, so you can write 1/2x instead of 1/(2x).

It depends on how much time you work on it each day. Math is learned through lots of practice. If you watch the videos and don't do any problems on your own, it's doubtful you would make any significant progress. Good luck with your class!
