I suspect the missing multiplication sign between the 2 and the (2+2) throws some folks.

BTW: MS Excel says 8/2*(2+2) = 16Ryan "ElDirector"

Do they still teach the Order of Operations these days? Or did Common Core kill that for some other ****ed up thought process

I'm with you guys but apparently we're all outdated...

This is the best explanation I've seen.

https://mindyourdecisions.com/blog/2...wer-explained/

My brain breaks it down as 8/(2*(2+2)) but everything I can find now (including most calculators, excel, and google sheets) breaks it down as (8/2)*(2+2)

Now I know why excel frequently divides things wrong and requires me to add more parenthesis...

It appears to be a change in the way expressions are written in print. In our time everything after the division symbol was the denominator. Apparently not any more.

The issue is weather we treat 2 * X the same as 2 * (X). There is no strict rule, unfortunately.

The CORRECT way to write the problem is either:

8÷2*****(2+2)

or

8 / (2(2+2))

Otherwise, it is open to interpretation, based on how you were taught.Ryan "ElDirector"

You need to complete the evaluation of the parenthetic term before performing the division. The expression is most correctly equivalent to (2 x (2 + 2)). Think of it as a fraction with 2(2+2) in the denominator

Edit:Corrected use of wrong termYou may not be interested in war, but war is interested in you

This is stupid, millennials are stupid, common core is stupid. The answer is one and it seems like everyone here knows it.
