I wasn't a great Math guy but I remember "orders of operation" from way back when...9

It is a math problem that appeared on facebook some time ago, some people argue to death and defriend each other arguing which is the correct answer for it, 9 or 1. Scandalous.

It's 1 following the parentheses rule, no?

You do the parenthesis first. Multiplication AND Division, you do whatever one comes first in the equation. So in this case, you divide first and then multiply.
(2+1) = (3) and then 6 ÷ 2 = 3, and 3(3) = 9

:cheer:

Technically can't that be written as 6÷2(2+1)= 6 ÷(2x2 + 2x1) = 1?

Then again I'm not sure. :lol:

No, because you do whatever is in the parenthesis first. So you Add 2 and 1 to get 3.

Then it's 6÷2(3)
