Question
Construct the composition table for +5 on set S = {0, 1, 2, 3, 4}.

Answer

a +5 b = the remainder when a + b is divided by 5.

eg. 2 + 4 = 6 ⇒ 2 +5 4 = 1 $\because$ [we get 1 as remainder when 6 is divided by 5]

2 + 4 = 7 ⇒ 3 +5 4 = 2 $\because$ [we get 2 as remainder when 7 is divided by 5]

The composition table for +5 on set S = {0, 1, 2, 3, 4}.

+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
