Question

Take suitable integers and verify the following.
1. Subtraction is not commutative.
2. Multiplication is associative.
3. Division is not closed.
1. Multiplication is distributive over subtraction.
Product of odd number of negative integers is a negative integers and verify​

Answer 1

1. let the integers be 3 and 5

3 - 5 = 5 - 3.

-2 is not equal to 2.

2. let the 3 integers be 2,4,5.

2(4× 5 ) = (2×4)×5

2(20) = (8) ×5

40 = 40.

3. let the integers be 2 and 15

2 ÷ 15 = 7.5 ( which is an decimal. )

4. let the digits be 4,2,1.

formula: a( b-c) = (a × b) - (a×c)

4 (2-1) = (4×2)-(4×1)

4 (1) = 8-4

4 = 4

hence,proven
