Numbers in Reverse

Name: _____________________ Date_____________


Steps
Example

1. Start with any number

87

2. Reverse the digits

78

3. Add

87 + 78 = 165

4. Reverse the digits

561

5. Add

165 + 561 = 726

6. Reverse the digits

627

7. Add

726 + 627 = 1353

8. Reverse the digits

3531

9. Add

1353 + 3531 = 4884

If you keep doing it long enough, a number will be reached that reads the same when the digits are reversed. Notice that 4884 reads the same from left to right as from right to left.

Try this with several numbers of your own choice.
