What grouping signs?

Do you mean PEDMAS

1)  do the stuff in the PERENTHESES first

2)  then do EXPONENTS (powers)

3)  Then do DIVISION and MULTIPLICATION. They are equally important.  Do them from left to right.

4) Then do ADDITION and SUBTRACTION. They are equally important.  Do them from left to right.
