Question

8. Show that the set of integer is commutative under addition and multiplication with an example. [4] Add film​

Answer 1

Answer:

In case of any two integers x and y,

x+y = y+x.

∴ 10 + (– 7) = (– 7) + 10.

Commutative Property Under Addition:

The addition is commutative for Integers

And again,

In case of any two integers x and y,

xy = yx.

∴ 10 x (– 7) = (– 7) x 10.

Commutative Property Under Multiplication

The multiplication is commutative for Integers
