you want to multiply 2 with the content of the parenthesis but also do the division between 8 and 2 so they're MD which leads you to use the rule of left to right and you're forced to do the division first.

math allows for interpretations (see geometry and euclidean/non-euclidean spaces, or degrees vs radians), but they ALWAYS lead to a single result.
8/[2(2+2)] interpretation is simply INCORRECT because there is no parentheses around 2*(2+2) in original question.
[8/2]*(2+2) is implied because that's what you get if you apply PEMDAS.

Well sadly for you it's a division operator and not a fraction implier. It's a common misconception which yields you the wrong answer. You need to define the parentheses explicitly to define correct fraction.
If you apply universal math rules on this equation you'll get the only answer (16). Otherwise you're just doing it wrong.
Math is universal and explicit.

Again, equation in OP is correctly formatted equation, you're just applying parentheses where in fact there shouldn't be any because you have a misconception about division operator.

It's 16, because you need to perform 8/2 and get that sum before you multiply it to 4, you add 2+2 first, and then multiply that by 4 since 8/2 == 4.

I also typed it into my Ti-84 plus to make sure, but if you wanna do it differently that's fine you'll just get the correct value for whatever language you think math is written in.

/biz the trick to this question is simply making people forget, wether it be PE-MD-AS or simple formatting

The question is formatted correctly, but some of you keep reading it as 8/[2(2+2)] there would be a LINE drawn under or it would be brackatted which would leave you of the answer over 1.

This problem is fully mathematical which is why you can punch it into an caculator and get 16.


The brackets will tell the USER to to this equation first, if there are none then the user will automatically go from left to right doing any patherness then exponents first multiplication and divison from left to right as well as adding and subtracting.

>>23676802
it's a shorthand of a mathematical rule, which makes it mathematical rule as well.
All operators are abstractions, or "shorthands", as you said, of one fundamental operation: increment.
>addition is incrementing x number by an y number - x+y
substraction is a subset of addition which is simply addition by a negative number - x-y=x+(-y). Or, as people call it - inversion of addition.
>multiplication is incrementing x number by and x number, but y times - x*y = x+x+...+x (y times)
division is an inverse of multiplication
>Exponentiation is multiplying x number by x, y times - x^y = x*x*...*x (y times) = x+x+...+x (y^(x-1) times)
obviously, square root is the inverse of exp
As you may note, the higher abstraction level of mathematical operator - the higher its priority when you apply calculations on the equation. Inverse operation has the same priorities as their counterparts. As you start "calculating" applying mathematical rules, you reduce the abstractions in equation into simplest ones, starting with the highest abstractions out there, than executing fundamental operations left to right, leaving only the answer remain. That's how computers do the math, and that's how YOU do the math leaving all the shorthands such as memorizing multiplication table or PEMDAS behind.
