Why the brackets?

So which one of you was right?

My Mrs?

im guessing the fact that he is liking the 210 answers, he must be that one

Putting something in brackets means you do that problem first. So (6x5)x7 means you do 6x5 first, which = 30. Then you multiply 30 by 7, which = 210.

They are 3 multiplications, so brackets would have no effect on which you solved first as they all have the same priority.

As a poster said, it could also be 657.

Erm, not if its algebra it couldn't.

That would be 6(x+y), and that is pretty worrying.
