Question

if a= -12 and b= -3. show that (a-b) is not equal to (b-a).​

Answer 1

Answer:

The above question is an example of commutative property of subtraction which is not satisfied.

Step-by-step explanation:

Given:-

a= -12

b= -3

To show:-

(a-b) is not equal to (b-a)

(a-b)

=

{(-12)-(-3)}

={(-12)+3}

={-12+3}

= -9

And,

(b-a)

=

{(-3)-(-12)}

={(-3)+12}

={-3+12}

= +9

Thus:-

(a-b) is not equal to (b-a) in the above problem as (-9) is

not equal to (+9).
