i think people have fried their brains & fed the wolf
rule of BODMAS applies here.
B = Bracket
O = Off
D = Division
M = Multiplication
A = Addition
S = Subtraction

So first solve bracket then so on...
6/2(1+2) = 6/2(3) = 6/6 = 1

the difficulty lies in the two arguements

BOMDAS
or
MODMAS

"These mnemonics may be misleading when written this way, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction."

It's 9

6/2(1+2)

[link to en.wikipedia.org]

"Today, parentheses or brackets are used to explicitly denote precedence by grouping parts of an expression that should be evaluated first."

"The order of operations used throughout mathematics, science, technology and many computer programming languages is expressed here:
exponents and roots
multiplication and division
addition and subtraction"

"Mnemonics are often used to help students remember the rules, but the rules taught by the use of acronyms can be misleading. In the United States the acronym PEMDAS is common."
"These mnemonics may be misleading when written this way, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction."

It's parenthesis first, then follow the standards for order of operations from left to right

6/2(1+2)
Parenthesis first: 1+2 =3
Multiplication and division are of equal precedence, but since division is farthest to the left in this problem, division comes next:
6/2=3

3x3 = 9
The answer is 9

Original Message 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 .
