 6 x (5 +3) = 6 x 8 = 48

or is this the answer?

 6 x (5 +3) = 30 + 3 = 33

So, long ago people agreed to always follow certain rules when doing calculations, and they are:

It makes a difference to the calculation which parts you solve first.

6 × (5 + 3) = 6 × 8 = 48
6 × (5 + 3) = 30 + 3 = 33 (wrong)

First the items in the brackets are calculated, then divide and multiplication, then addition and subtraction.
