Order of Operations

K-3 Themes

In mathematical expressions, the standard order of operations is:
  1. Parentheses and other grouping symbols
  2. Exponents (powers)
  3. Multiplication and Division - done in order from left to right
  4. Addition and Subtraction - done in order from left to right

One easy way to memorize the order of operations is to use the mnemonic "Please excuse my dear Aunt Sally."

Some examples:
50 - 2 x 6 {do the multiplication first}

= 50 - 12

= 38 + 1

(4 + 3) x (5 - 4) {do the two sets of parentheses first}

= 7 x 1

= 7

40 - (16 ÷ 2) x 4 + 1 {do the division first}

= 40 - 8 x 4 + 1 {do the multiplication}

= 40 - 32 + 1

= 9

11 + 4 x 32 - (6 + 5 x 2) {do the exponent and the multiplication inside the parentheses first}

= 11 + 4 x 9 - (6+10) {do the multiplication and the addition inside the parentheses}

= 11 + 36 - (16)

= 31
