Answer -
1 +5 1= remainder obtained by dividing 1 + 1 by 5
= 2
3 +5 1= remainder obtained by dividing 3 + 1 by 5
= 2
4 +5 1= remainder obtained by dividing 4 + 1 by 5
= 3
So, the compositiontable is as follows:
| +5 | 0 | 1 | 2 | 3 | 4 |
| 0 | 0 | 1 | 2 | 3 | 4 |
| 1 | 1 | 2 | 3 | 4 | 0 |
| 2 | 2 | 3 | 4 | 0 | 1 |
| 3 | 3 | 4 | 0 | 1 | 2 |
| 4 | 4 | 0 | 1 | 2 | 3 |
