    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 ) .
