  1. Possible response: I know 5 × 7 = 35. Since 5 × 3 = 15, I subtracted 35 − 15 = 20 to find the missing number.

MM. Missing Numbers

Find the missing number in each equation.

  1. 120 − = 10 × 10
  2. 60 − 20 = 8 ×
  3. 35 + = 10 × 7
  4. 10 × = 60 + 30
  5. 30 + = 5 × 9
  6. 5 × 7 = (5 × 3) +
