    Thanks Jason. I'm 71 now and finally get it. Just wish I had you for a teacher 55+ years ago. 5 algebra regents to finally pass with a 67. Just couldn’t understand foreign languages; algebra, French, music.

    Good afternoon Jason from Math and Science, I am not sure that you preferred to be called Jason or professor.
    My name is Marcia Jacobs presently attended Queens Borough Community College fall semester of 2021, subject taken was math 119.
    Prior to taking Math 119 Fall semester I reviewed basic math and pre algebra you really showed me that I missed the concept in high school and any student whom watched your instruction in basic math, pre algebra and college algebra will never failed math again. your instruction, illustration and information was enforced, points made was very strong after watching your videos on youtube I will meet my goal in math. After all pre algebra in High School seem like it came out of the twilight zone, my highest score in high school was 75, now I feel very confident of 100 which is my goal.
    I would like to take the time to Thank You for sharing your resources on youtube which help a novice student while I took math and expecially during Math 119.
    Hoping you and your family had a happy holiday and a happy new Year. Many blessing in future endeavour.
    Thank You
    Marcia Jacobs

    This isn’t actually 100% exhaustive. You first do implicit inside *and* unimplicit parenthesis outside the parenthesis.
    For example 2/4(8) is not equivalent to 2 / 4 * 8, but to 2 / (4*8): since in this case 2/4(8) is actually 2/32 2/(4*8) or 2 / 4(8). You see this very commonly with cases like 2/ 4a where a in this case where a is 8
    This is what causes so much confusion on these popular meme posts where people argue over endlessly without fully understanding the issue. It doesn’t change the order of operations at all, it is just a more natural way of markup that reduces implicitly declared properties which you do need to add for computers

    we learned the method of "PEMDAS" and it really confused me because one of my biggest downfalls is asking waaayyy oo many questions in my head that confuses me, but anyway, out of 50 stars, im gonna say how much I understand orders of operation and hopefully one day it reaches 50

    @johng.1703 Год назад

    when you realise the 7*3 is 7+7+7 you can start with addition and end with addition. the reason you don't add to a multiple is because the two terms are multiples, so in this instance 7*3 is either 3 lots of 7 or 7 lots of 3, if you added the 2 to the 3 you would be doing 5 lots of 7 / 7 lots of 5. so you would be adding 14 not 2. you can actually do the addition first as long as the addition is a multiple of one of the terms and you add it as a multiple, for instance 7*5+10 10 is 2 lots of 5 so you could add 2 to the 7 and you would then have 9 lots of 5.
    when you understand what is actually happening and why you need to carry out the operations in a specific order, you no longer need to follow that order. you can do it in any order you like as it is all addition and you can do addition in any order you like.

    How would you solve this? "8 / 2(2+4) = " I say it is 8 / 2(6) =, then 8 / 12 = 2/3 or .6667. The question is whether you FIRST multiply the outcome of the parentheses by the 2, or divide 8 by 2 and then multiply by 6 = 24. All of your examples BEGIN with the parentheses, but I have seen none like my example.

This one is just the most generally accepted way in most countries with very few differences. However, if you go to more abstract or more mechanical ways, thigs do change due to optimization or markup differences. For example a common difference is 4*2 /3( 3+ 5) and 4*2 % 3(3+5) where % is that other division symbol I don’t have on this keyboard layout.

    The problem 48÷8(14-8)= i get 36 yet people say 1.. i know they are getting 1 because they are keeping their parenthesis values in parenthesis after the fact. I just want to know which is right and why is there such a mix-up

    • @MrGreensweightHist
      @MrGreensweightHist Год назад

      36 is the correct answer.
      This is going to get a little long winded, sorry.
      The reason people keep, mistakenly, attaching the 8 to the parentheses is because they are misunderstanding something called "Implied Multiplication"
      There is a rule that you have to keep a coefficient and its variable together.
      2a is one term. It must be treated as a single term.
      This multiplication is the HIGHEST priority because that term is inspirable.
      It is called implied multiplication because you don't actually have a operation sign telling you to do it.
      It is also called multiplication by juxtaposition. The word juxtaposition means side by side.
      When they see 2(x) they don't see a multiplication sign and think that is also implied multiplication.
      They do not understand that (), unless another sign is put in front of it, counts as an explicit multiplication sign, and is not "implied"
