Answer 1

Brackets ([]) are simply parenthesis outside a set of other parenthesis.

Look at it like this:

3(10-(27/9))

3(10-(3))

3(7)

21

Answer 2

Well you're going to want to start off inside.

So bring it to 3[10-(3)]

And once again, that is simplest, so figure 10-3=7

So now you're left with 3(7) which is simply 21.

Hope that helps!

Answer 3

first you want to so the problem in the inside brackets 27/9=3

and the 10-3=7 then 7*3=21
