Tomorrow i have a super big quiz about PEMDAS and i only understand what the word means, can somebody make an example of a big problem and resolve it with PEMDAS?

I would post a big problem but it was already proven, by top mathematician Terence Tao, that it is impossible to compute your mom's weight.

Oooohhhhhh snap!
>>7796803
is this just semantics or is there an overarching mathematical reason why this is the order we do things?
Examples only work if you have an Aunt Sally

It is literally the government accepting the fact that kids are retarded and just applying rules.
PEMDAS goes completely against BODMAS. A kid in one system would first multiply while the other kid would first divide.
And that may be silly but it is even more silly when you realize that multiplication and division are literally the same operation. Just like adding and substracting, you just change the 'parameters' for the additive or multiplicative inverse.
I just use parenthesis to define the order I want you, the reader, to see the calculations. That is the best way and is completely unambiguous.
Your government thinks you are too stupid for parenthesis.
44-62/4*2+14

44 - 6^2 / 4 * 2 + 14
= 44 - 36/4*2 + 14
= 44 - 9*2 + 14
= 44 - 18 + 14
= 58 - 18
= 40
How's the second grade?
