48÷2(9+3) = ???

Alright, left this topic only to find out it's even worse than before.

To those who posted this link, http://www.purplemath.com/modules/orderops2.htm about the parenthesis making the multiplication stronger it leaves me to this conclusion to which the author already stated: it's inconclusive.

Why?

If you enter that same problem(either the example they give or the one we're talking about) in a calculator, Wolfram Alpha etc. and change the brackets to parenthesis and vice verse, the answer is completely different.

48÷2[9+3] comes up to 2 while 48÷2(9+3) = 288 which makes no sense at all. So we can argue all day but it seems that no one can give a definite answer. There is multiple sites saying you only complete what's in the parenthesis/brackets while the link above has a rule that either not a lot know or consider.

By convention, the order of precedence in a mathematical expression is as follows:
Terms inside of Brackets or Parentheses.
Exponents and Roots.
Multiplication and Division.
Addition and Subtraction.
If there are two or more operations with equal precedence (such as 10÷2÷5 or 7÷2*9), those operations should be done from left to right.
Therefore, the problem “48÷2(9+3) =â€

To the dude who said 4(5-2) = 28

Durty pancakes there is a difference between 2 * (9 + 3) and 2(9 + 3). If the question was 48/2 * (9 + 3) the answer would be 288. But being the 2 is attached to the brackets you have to do the entire bracket formula of 2(9 + 3). The 2 being attached means you must include that in the equation. If it was 2 * (9 + 3) then you don't HAVE to multiply it by 9+3.

This is redonkulous.

100+ pages over a damn math question..?

I hope some of y'all feel accomplished

the answer is 2.

this is true, but it being a 3 term problem is not. the division sign implies that all of 2(9+3) is in the denominator. otherwise, the problem would be written different.

... You're going right to left, though. You were probably taught by all the brilliant mathematicians who belong to Team 2.

how am i going right to left?
are you saying the 2 should NOT be distributed/multiplied into the parentheses after you add 9+3?

THIS.
i didn't wanna say it until someone mentioned it. x/2(9+3) is NOT the same as x/2*(9+3). The division sign makes a hell of a difference in this case.

105 pages tho hahah clear what kinda board members we have here, I got 2 at first glance but I dunno seems pretty corny to argue over, its math... There is no logic but its logic and when logic belies it rules are made up to create a truth.

2+2 =4
Or
2+2=elephant

?
