There is a pretty extensive debate on another forum about this problem. Some answer it as 9, others answer it as 1. Can someone please give me an outsiders perspective on this? What is your answer? How did you reach it?

## Re: 6÷2(1+2)=?

See, I got 1 as my answer, but I've been away from school for 12+ years so...I'd ask for a second and third opinion. This is how I got it:

6/2(1+2) ------> At some point I was taught that anything in parenthesis is always done first, which means this would be next:

6/2(3) -------> multiplication is supposed to follow so then:

6/6 and..

1 tada!!

But like I said, I've been out of school for way too long. I hope this helps and if needed, please correct me.

## Re: 6÷2(1+2)=?

Multiplication and division are done with the same precedence from left to right, so we would have:

6/2(1+2) = 6/2(3) = 3(3) = 9

If we wish for the division to be done first, then we would write:

6/(2(1+2))

As it has been given though, is the same as:

(6/2)(1+2)
