We can because A(B) = A x B basically

I don't remember them teaching us that you get marks for re-writing the question.
2x(2+1)= 2x2 + 2 = 4 + 2 = 6 as well.

Is that by following rules or common sense?

No it's not.

6÷2(2+1) is the same as writing 6÷2 x (3).

The first two are grouped and then the second. You go in order of operations at that point and you go from left to right so you divide first and then multiply.

This problem is pretty clear if you know the rules properly

I think this thread should just burn to death in a pile of random gifs.

Like I said, I know that but removing the bracket and writing it as 2 x 3 separates them both so the 6 gets involved with the 2 and 3 is like "wtf bitch back off" and 7 ate 9 and they all got into a fight.

The brackets don't give whatever is adjacent to them any special priority when it comes to multiplication. Read Inger67's post for a more detailed explanation
