Have you seen this on the web? Can you solve it? 8÷2(2+2)=?

Yeah, its a trick question it depends on what system of hierarchy of the operations that you use. The answer is either 1 or 16 (PEMDAS or BODMAS respectively).

8÷2(2+2)=?

4 x 4 = 16

The problem is written incorrectly and is ambiguous. Both 1 and 16 can be correct.

Correct, the use of the division symbol (÷) is discouraged for this reason.

8 / 2 * (2 + 2)
Parentheses first so resolves to
8 / 2 * 4
Preliminary work done, now start over
Division and multiplication are of equal precedence so evaluate left to right
8 / 2 = 4
4 * 4 = 16

PEDMAS

Means you do parentheses first (P)
Exponents next (E)
....

BUT what they don’t always say is you do all your Multiplication and Division at the same time “LEFT TO RIGHT”....

Which means it’s = 8/2(2+2)

Converts to 8/2*4... which is done strictly left to right...

OR. 4*4 =16

So there is only one correct answer. smile

PEDMAS - if only it was that simple. In C programming language:

So I use parentheses freely, helps keep you sane.

Oh I see, the expression isn't ambiguous, people don't understand the mnemonics.

It’s a common mistake to keep working from where the paran’s where but that means working “right to left” vs. left to right... (and that is arse backwards).. and results in a wrong answer.

Here's one of the comments from the article:

8÷2X(2+2) = 16
8÷2(2+2) = 1
Final answer.
People who are poor in math will add that multiplication sign in their delusional minds and then follow PODMAS to come up with 16
People who are proficient in math will not add that multiplication sign and still follow PODMAS exactly and come up with 1.

To get 1, you have to add a set of parentheses: 8÷(2(2+2)) = 1

Didn't study for a pop quiz this morning. I thought the always correct answer was 6.5
