  1. Inverse Operation • MA.7.1.3: • By , • Period 1

  2. Inverse Operation An Inverse operation ‘reverses’ another operation. Addition and subtracting are inverses of each other. Because Adding and subtracting the same number does not change the original number.

  3. EXAMPLE X + 8 = 11 - 8 = -8 X = 3

  4. Problem • Solve for x • x+2 =8

  5. Solution! 8 - 2 = 6 subtract 8 by 2 =6 X + 2 = 8 - 2-2 X=6 Check: 6 + 2 =8

  6. Credits • Thanks to Mr. Imamura • Brianna Akau- Thomas • www.google.com • http://www.sparknotes.com/math/prealgebra/operations/terms/term_9.html
