Hello,

So, me and my older brother are in a math debate. The debate is about an article we saw. The article states that many people are being stumped by simple math problem. The math problem is the following:

6÷2(1+2)

My brother did it this way:

6÷2(3)

6÷6

1

I did it this way:

6÷2(3)

3(3)

9

Here is the debate. It is about PEMDAS. My brother says that you should do multiplication first then division.

I say that whatever comes first, you do that first. In this case, division came first.

As you can see, we both got different answers. Who is right? Me or my brother?

Can someone help me settle this debate?

$6 \div 2(1+2)$

$6 \div 2(3)$

$3(3) = 9$

Jared you right PEMDAS, whatever order comes first is the one that should be done. Answer is 9.
