Answer 1

Answer:

yes a+b is an integer because a and b are integer s

Answer 2

Answer:

Step-by-step explanation:

f a and b are two integers , then a-b is also an integer?

The answer is yes!

If a and b are two integers then,

a + b = integer

Example = -4+8 = 4

a - b = integer

Example = 10 - 8 = 2

b - a = integer

Example = 8 - 10 = - 2

b + a = integer

Example = 2 + -3 = -1

But do whole numbers satisfy the same property?

The answer is no !
