Order of Operations Using Integers

“Operators” & “Terms”… 12 • -5 + -3 • -6 Terms Operators

What do we do first???? It Matters!!!! -5 + 7 • 10 = -5 + 7 • 10 2 • 10 20 -5 + 7 • 10 -5 + 70 65 It Matters!!!!

The Order of Operations All of Algebra is Based on… The Order of Operations 1. Parenthesis 2. Exponents 3. Multiplication & Division (left to right) 4. Addition & Subtraction (left to right) 5. Simplify any Fraction

What do we do first???? 5 + 7 • 10 = 5 + 7 • 10 12 • 10 120 5 + 7 • 10 5 + 70 75 5 + 7 • 10 5 + 70 75

The Order of Operations Memorize These 1. Parenthesis 2. Exponents 3. Multiplication & Division (left to right) 4. Addition & Subtraction (left to right) 5. Simplify any Fraction

Example 1 -2 -2 + 6(-8 + 5) -20 42 - 6 10 -2 + 6(-3) 42 - 6 -2 + 6(-3) Holy Mackerel -2 + 6(-3) 42 - 6 -2 -2 + 6(-3) 16 - 6 -2 + -18 16 - 6

Example 2 12 • -5 + -3 • -6 -60 + 18 -42
