Re: Math: 6÷2(1+2) = ?
Order of operations

PEMDAS

parentheses

exponents

multiplication and division

when two operations are of the same rank they are done left to right.

So first do parentheses leaving you...

6 divided by 2(3)

since the only thing left is multiplication and division you now go left to right.

six divided by 2 = 3

and three times three = nine.

The confusion seems to be from the fact that people believe that each individual letter of PEMDAS is done in that order. In which case multiplication would come before the division. But this is not so. Multiplication and division is done left to right.

Order of operations:
Rule 1: First perform any calculations inside parentheses.
Rule 2: Next perform all multiplications and divisions, working from left to right.
Rule 3: Lastly, perform all additions and subtractions, working from left to right.

Re: Math: 6÷2(1+2) = ?
well let's see... it we take 8 and add it after it's subtracted and then place a 1 at each end only to subtract 2 in the beginning before I came here... then the answer would be 52-43

Thank you Thank you I am smart and good looking... not to mention...modest !

Here is a great pic of me giving a speach...

I have always used BODMAS [link to www.mathsisfun.com]

B - Brackets first
O - Orders (ie Powers and Square Roots, etc.)
DM - Division and Multiplication (left-to-right)
AS - Addition and Subtraction (left-to-right)

PEMDAS

6÷2(1+2)
P - 6÷2(3)
E - there are none
MD - 6÷2(3)= 3(3) = 9

It IS a trick question because the arithmetic layout is ambiguous.

6÷[2(1+2)] = 1

(6÷2)(1+2) = 9

It's not a difficult problem, it's just laid out wrong.

The question is deliberately ambiguous and that people get different answers is of no surprise.

Why is this so difficult for people? I'm fairly dyslexic, but I have still managed to do allot of mathematics and physics in college etc. This is very sad that such a simple operation is essentially impossible for many people.

You are retarded, its not a trick, its the rules of math, short notation maybe, but certainly fair game for second or third grade.

Alright, there's a lot of self-proclaimed experts around these parts. Let's see how your logic holds up against some basic mathematics.

6÷2(1+2) = ?

I'll give two hints. This is NOT a trick question, and there is only 1 correct answer.

All tools used for computation are fair game.

(Yes, I saw this somewhere else and decided to post it here.)

Best of luck to all you geniuses .

This is the best GLP social experiment I've ever seen.
Well done!

1.) OP posts an initial question
2.) Correct answer is given within the first 3 posts
3.) Everyone continues to call eachother an idiot, wrong answers are given
4.) An argument about the process is discussed
