Question

What happens when we subtract one integer from another? Does their difference is also an integer? Complete the following table by observation:

S.No	Statement	Observation
1.	7 – 5 = 2	Result is an integer
2.	4 – 9 = -5	………….
3.	(-4) – (-5) = ….	Result is an integer
4.	(-18) – (-18) = ..	………..
5.	17 – 0 = ….	………….

Answer 1

S.No	Statement	Observation
1.	7 – 5 = 2	Result is an integer
2.	4 – 9 = -5	Result is an integer
3.	(-4) – (-5) = 1	Result is an integer
4.	(-18) – (-18) = 0	Result is an integer
5.	17 – 0 = 17	Result is an integer

From table it ¡s clear that when we subtract one integer from another integer then remainder is also an integer. Therefore difference of two integers, is also an integer.
