    Sally (subtract

    1. parentheses

    2 exponets

    3 mulitiply/divide

    4add/subtract

    *left to right*

    9+3=12+2=14  18-14=2

    i think thats how u do it. havent done it for a while!


  2. Work from inside the parentheses out:

    18 - (9 + 3) + 2

    18 - 12 + 2

    6 + 2

    8

    One way to remember the order is the phrase: Please Excuse My Dear Aunt Sally.

    Parentheses first, followed by exponents. Next come multiplication and division. Finally, the last two operations performed are addition and subtraction.

  3. 18-(9+3)+2 =

    18 - (12) + 2 =

    18 - 12 + 2 =

    8
