I just want to say thank you for making it so easy to comprehend. I really struggled with math since the sixth grade because my math teacher really traumatized me and belittled me in class so ever since then my mind would literally shut down when it came to algebra. I failed many tests because of it and it's something I always tried to overcome and get better at. Thanks to you I've been able to solve most of these problems you present here and I'm really happy about that! I'm no longer afraid to try and solve math problems. I'm very close to being sixty years old but I'm not one to give up on something I really want to learn. You have been the only one I can really learn from and believe me I have tried learning from others but for some reason it just would never stick to my brain lol So thank you for doing this, you truly have a great gift to teach, especially for those like me that struggled for so long.

Ah, sometimes the people who are teaching us can have good intentions, but quick to judge. I know of someone who their own father who used to help him with studies said that he should never do anything math related. I still remember the day when it happened to him. He himself had barely passed his middle school math exam and could not understand algebra. But, as incredible as this might sound, he was amazing at math in high school. On super difficult math exams, he would be the top scorer in the entire school. He got into Engineering with one of the top scholarships, was the top scorer in math exams at the University, went onto complete his PhD in the same field lol. He also partly credits one of his high school teachers that really motivated him and also made things click for him. Imagine if he had completely given up.

Not once in school was M/D and A/S described as a set (and subsequent "switching" of the order of those operations depending on left to right where they fell in the equation) the way you did it. Now, after watching this, I understand. Great job in clearing that up.

Thank you. I'm 73 years young. My father was a middle school math teacher, and I could never get it. Teachers would be filling up the black board with figures, and filling up the air with words. Other students were asking pertinent questions, but to me the whole thing was gibberish. A teacher friend showed my wife and me a VHS video from a conference on learning disabilities that he attended, with the thought that it might be relevant to some problems our son was experiencing. It was a life changing moment for me. I didn't see my son. I saw myself. I was always considered to be intelligent, but in school, was getting D's and F's in math. With your channel, I can pause, repeat, and work my way through at my own pace, and I can get it.

My experience with math teachers during all my school years was very negative because the teachers only liked the students who got the lessons the quickest. I got some things right away and other things I did not as I found some concepts to be more complex and needed a little longer to work through it. If all my math teachers were like you, I would have had a very good experience with math. It's not that I hate math I actually like it especially working with equations ie algebra.

It has been a while since I’ve done this math. Your explanation was excellent. Figured it out as soon as you go to MD. Thanks

Thanks Aunt Sally, you’re the best!

I’m 75 and finally learning algebra with your great teaching. I attempted algebra in grade 9 but just couldn’t understand it and gave up, but always wished I knew how to do it. I never knew pemdas so glad I’ve learned it now. I’m struggling somewhat with the algebra but catching on will take some practice and I’ll keep watching your videos. It’s never too late to learn! I’ve also taken up drawing and painting at this age and actually doing pretty good with it, I never thought I could draw.

Having teachers that can communicate in a way students understand and can figure out how to make math fun and relevant helps with students succeeding as well. I had some really great teachers who knew how to teach without us realizing we were learning. I’ve also had teachers who basically said “read the book. Ask your parents or figure it out”. And that’s when the overwhelming frustration starts, followed by the “Why should I bother?”

There was a lot of stuff happening in my life when I was supposed to be learning this. Thank you so much for teaching this. I love solving problems now.

This man is a very good teacher! A lot better than the ones I had in high school or college. Except for one college professor who was originally from China. He was a very patient man who made sure everybody he could learn how to solve the math problems.

I was taught BODMAS in school; brackets of, division, multiplication, addition, subtraction. Therefore brackets: 18/2 = 9 x 3 = 27 + 2 = 29 … 7 x 29 = 203

Greetings. Yes we can. The answer is 203. The bracketed portion works out to be 29 which is then multiplied by 7 to get 203. How did we do it? First, we start with the bracketed figures. In the brackets, we first divide 18 by 2 to get 9, we then multiply 9 by to get 27, 27 is then added to 2 to get 29 and thereafter we multiply 29 by 7 to get 203.

Answer 203. Before watching a few of your Math Class vids I would not have calculated this properly. I never understood what came first or what I was supposed to do with the number outside the brackets. I never had a proper math teacher in either primary or secondary school, so I concentrated on every other subject and gave up on math. You have now restored my faith in myself and I shall stop telling people I was never any good at math. I could have been if I was taught. What a shame I've only discovered the rules at this end of my life. In case you're wondering - this is not a result in a lack of education, I had 2 Masters degrees (in Literature and Ancient Languages) and a PhD in History and Medieval Languages. Note, none of these involve more than a rudimentary knowledge of math. So again, thank you so much.

I love watching and learning your math problems!

When I was in school in Canada in the 1960s, I learnt that it should not matter whether PEMDAS is left to right or right to left. It was always P, then E, then M, then D, then A, and then S in the order of operations. I would read this as 7[2+(18/2x3)] = 7[2+(18/6)] = 7(2+3) for a solution of 35. I thought the same principle of direction applies to all math problems, i.e., the end one begins should not matter. Do you happen to know when MD and AS were grouped and PEMDAS went left to right?

I am 79 and enjoying your math instruction. Pity you were not around as a teacher 67 years ago as my math teacher.

As I understand it, what is in parenthesis is calculated first. Division and multiplication come before plus or minus but they are equal so you calculate them in the order in which they appear. Therefore 18 divided by 2 = 9. Then multiply 9 by 3 which = 27. Then then the addition in the parenthesis means 2 + 27 which is 29. The 7 outside the parenthesis is now multiplied by the number in the parenthesis, so 7 x 29 = 203.

And I thank her/him even though they have probably have passed on.

When working a complicated equation, you have to look at the large picture and deal with the top priorities first. In this situation, the top priority is the brackets. This means that you have to complete this equation inside the brackets before going to anything outside of them. Within the brackets, you have a division sign and a multiplication sign that take equal priority over an addition sign. Doing the higher priorities first, and left to right, you have 18 divided by 2, which equals 9, and then 9 x3, which equals 27 as the total of the two operations. Then the 2 is added to 27 for the final operation within the brackets, which equal 29. Then you go outside the brackets and take the 7 and multiply by 29, which equals 203. The brackets( which are indicating to multiply the result within the brackets(29) to the result outside the brackets, which is simply the number 7) take the highest priority in the total operation for the very reason I have given to you within THESE brackets. So, 203 is the correct answer. Thank you, Ruth Coffey!

I was 11 years old and failed at maths again and again, despite excelling in other subjects at secondary school. I find public speaking difficult to this day.

I got an answer of 35. I believe I learned to do what's inside parentheses, with multiplication first, then division, then addition, then subtraction, then what's outside the parentheses. Therefore, 2x3=6. 18/6=3. 3+2=5. 7x5=35. Now I'm going to watch the video and see if I remembered correctly, although I've always been horrible at math. I do believe (there was no such thing when I was a kid) that I have a math learning disability, or the "new math" of the 1970s left me with one. EDIT: Okay, so PEMDAS is pretty much what I learned, or at least the MDAS portion, but never switching the division and multiplication. Never. Because then it would be PEDMAS. I guess my entire academic career taught me WRONG. No wonder I can barely add 2+2 these days, and I'm 58 years old.

I've never liked "PEMDAS" acronym, somebody invented that after I graduated from high school and I think it's stupid because it's misleading. It makes it look like each letter is its own step. But as shown in the video here - which is the correct way to solve the problem - the MD is a single step. Multiply and divide have EQUAL priority, which one "goes first" literally depends how the problem is written from left to right - which one do you run into first as you read the equation? Then it's the same story for the AS - it is a single step where both addition and subtraction have the same priority. So really I think it should be written like this "P/E/MD/AS" or something instead of just "PEMDAS". If that makes sense. So what I learned to do, and this is something I taught myself because I'm a frikkin GENIUS... is before I even try to do ANY of the math I'll do two things: 1. Rewrite any division as a FRACTION. This prevents me from getting confused about which terms go into the division after I start doing the math. 2. Rewrite any subtraction as a NEGATIVE addition, this way the negative sign will move with the number but I can move the operation around the equation like a regular addition task if I need to reorganize the way it's written out. I don't know if you've started learning about negative numbers yet but if not then I'm sure you'll learn about them soon and you can start using this step once you do. Remember that these two steps I mention are only for the purposes of better clarity in the way the problem is written. I haven't actually done any math yet. So those steps are optional, but personally I find them to be pretty useful just for the sake of keeping things organized as I start moving numbers around. Also remember that these two little steps must also follow the same basic rules as "PEMDAS."

I was halfway there. Forgot to multiply my seven. Thank you for sharing. I’m loving this.

On the final step. Because I don't know off hand what 7x29 is. I multiply 7x30 which I know is 210. I can do that in my head. Then I subtract 7 which gives me 203. I learned this in school in Canada in the 70's rounding numbers up or down to the nearest 10 then subracting or adding the number your multiplying by. It just makes it easier to calculate in your head.

Thank you! I completely got this wrong because of the left to right order. Great explanation.

It's amazing you know on Facebook (I came off FB about 2 years ago) that when these questions came up, the amount of people who would argue with the Order of Operations and how they "were not taught that when they was at school" and how "it's all wrong and made up recently". Some of these people were so called teachers! One of the reasons I came off FB to be honest as I found myself involved in those arguments pointing people to links and references about OoO and how it stemmed back hundreds of years lol I do love watching these though even if it is just to check my ageing brain is still somewhat with it

Don’t ever remember learning BODMAS and with PEMDAS I was told to apply from left to right like a lot of people here are saying. I wish I had more resources like this when I was struggling in math

Excellent explanation, many thanks.

For everyone still curious, PEMDAS should really be written as PE(M/D)(A/S), as multiplication or division, then addition or subtraction, are done left to right in the equation. If division came before multiplication, that's how you would simplify the equation, or vice-versa. Same would be applied to addition and subtraction. If subtraction comes before addition, that is how it would be applied.

For those getting hung up on the MD and order to perform the operation, remember this: division is just multiplication by the inverse. So 8 ÷ 2 is the same as 8 x ½ . Same operation will always then go from left to right. Same thing goes for the AS: subtraction is just adding the negative of the number. So 5 - 2 = 5 + (-2) and then again - perform in order left to right.

7(2+27)=7(29)=203 the “My Dear Aunt Sally” has to be performed inside the parentheses first.

The answer is ambiguous because the question is asked in correctly. Use appropriate parentheses and to clarify the ambiguity. Like Excel forces you to do.

When I learned the order of operations in middle school, my teacher didn't use PEMDAS, he taught it as the 4 Ps. Parentheses, Powers, Product&Quotient (left to right), Plus&Minus (left to right). It might be a bit weaker as a mnemonic device, but since it included the grouping, it helped me to avoid the "taking PEMDAS literally" trap that some fall into. Mr. Heisman was an amazing math teacher.

7:00 you do not need to do it from left to right but only in the correct order. You can multiply first, but then you need to understand, that it is 18×3 because the multiplication refers to the dividend of the division but not to the divisor. So 2×3 is wrong.
