first for the parenthesis then for the power then / and * same order but prefer * then + - same order

1) parenthesis ()
2) Power ^
3) * then /
4) + , -

3. ## OK

B Brackets first
O Orders (ie Powers and Square Roots, etc.)
DM Division and Multiplication (left-to-right) " can do either of them "
AS Addition and Subtraction (left-to-right) "can do either of them"

Hope this helps.

BODMAS - Brackets , division , multiplication , addition , subtraction.

You do whatever that is in the brackets first , followed by division or multiplication ( in left-to-right order ) . Then you do addition or subtraction ( in left-to-right order ) .
