2: Next perform exponents.
3: Next perform all multiplications and divisions, working from left to right.
4: Lastly, perform all additions and subtractions, working from left to right.

Examples:

  1. 2 + 3 x 4
    = 2 + 3 x 4 ------ Multiplication
    = 2 + 12 ------- Addition
    = 14
  2. 32 16 - 2
    = 32 16 - 2 -------- Division
    = 2 - 2 ------- Subtraction
    = 0
  3. (12 - 10) x 5
    = (12 - 10) x 5 ------- Parentheses
    = 2 x 5 ------- Multiplication
    = 10
  4. 2 + 2 x (1 + 2) 3 - 7
    =2 + 2 x (1 + 2) 3 - 7 ------- Parentheses
    =2 + 2 x 3 3 - 7 --------Multiplication
    =2 + 6 3 - 7 ------- Division
    =2 + 2 - 7 -------- Addition
    = 4 - 7 ------- Subtraction
    = -3
  5. 32-2(4-2)+32
    =32-2(4-2)+32 ----- parenthesis
    =32-2(2)+32
    =32-2(2)+32 ------- exponents
    = 9 - 2(2) + 9 ------- multiplication, adding and subtracting
    = 9 - 4 + 9
    = 14
  6. -22+ 4 + 2
    = -4 + 4 + 2 ----- exponents
    =2
  7. (-2)2+ 4 + 2
    = 4 + 4 + 2 ----- exponents
    =10

Directions: Evaluate each expression using the correct order of operations. Also write at least 5 examples of your own.
