  1. How can you use parentheses to make an equation true? 12 - 9 - 3 = 6 /

  2. In this lesson you will learn how to make equations true by adding parentheses.

  3. Parentheses show us what to do first. Sarah bought 2 red scarfs and 4 blue scarfs. Each scarf cost $10. How much money did Sarah spend? Find the total number of scarfs first, so we can multiply by the cost. ( 2 + 4 ) x $10

  4. Not realizing that parentheses can change the outcome of an expression Example 7 x 4 - 3 = 7 x (4 - 3) = - 3 = 7 x 28 1 = 25 7

  5. Add parentheses to make the equation true 15 - 7 - 2 = 10 15 - 7 - 2 = 10 ( ) / / / / / / / / / / / = 10 5 15 - / / / / / = 10 / 6 10 = 10

  6. ( 18 + 6 _ 3 = 8 ) 1 Add parentheses to make the equation true 2 18 + 6 _ 3 = 8 3 4 5 + 6 7 8 24 _ 3 = 8 18 + 2 = 8 8 = 8 20 = 8 /

  7. Add parentheses to make the equation true 4 + 2 x 3 = 18 ) ( 4 + 2 x 3 = 18 + 6 x 3 = 18 4 + 6 = 18 10 = 18 / 18 = 18

  8. In this lesson you have learned how to make equations true by adding parentheses.
