  1. By Richard Castillo Inverse operations

  2. Definition The operation that reverses the effect of another operation.

  3. Example 10 + 20 = 30 30 – 20 = 10 The same numbers in reverse.

  4. You can do these problems with addition, subtraction, multiplication or division.

  5. How to For example, if you start with the number 6, and then add 4: 6 + 4 = 10 to get back to the 6, you have to subtract 4 from 10: 10 – 4 = 6

  6. With and 14 × 4 = 56 56 ÷ 4 = 14 The same numbers in reverse.

  7. Examples The inverse operation of 10 + 9 = 19 is 19 – 9 = 10 and The inverse operation of 7 × 9 = 63 is 63 ÷ 9 = 7

  8. Problem Identify the inverse operation for 14 × 4 = 56 Choices: A. 56 ÷ 4 = 14B. 56 × 4 = 14C. 14 ÷ 4 = 56D. 56 - 4 = 14 The answer is A.

  9. Two operations are said to be inverse to each other if one operation undoes the effect of the other operation

  10. The End
