METHOD
Step 1. Multiply the original number (Multiplicand) by 100, or just add two zeroes (00) at the right-hand end of the number
Step 2. Subtract the original number or Multiplicand from the new number worked out in Step 1
Step 3. The difference is the answer.
Example 1. Consider 5 x 99
Step 1. 5 x 100 = 500 or 500
Step 2. 500 - 5
Step 3. Answer 495
Example 2. Consider 67 x 99
Step 1. 67 x 100 = 6700 or 6700
Step 2. 6700 - 67
Step 3. Answer 6633
Example 3. Consider 4813 x 99
Step 1. 4813 x 100 = 481300 or 481300
Step 2. 481300 - 4813
Step 3. Answer 476487
| Number | Step 1 | Step 2 | Step 3 |
|---|---|---|---|
| 5 | 5 x 100 = 500 or 500 | 500 - 5 = 495 | 495 |
| 67 | 67 x 100 = 6700 or 6700 | 6700 - 67 = 6633 | 663 |
| 4813 | 4813 x 100 = 481300 or 481300 | 481300 - 4813 = 476487 | 43317 |
