Question

11. If a = -9 and b=-6 show that la- b) = (b-a).​

Answer 1

to show that

(-9-(-6)=(-6-(-9)

-9+6=-6+-9

lhs=rhs

-3=-3

actually inthe first answer

that person did wrong

like this

-9+6=-6+9

so here - 9 + 6 is equal to minus 3 and minus 6 + 9 is equal to 3 this is wrong

and in my sum I did minus 6 × minus so I got 6 plus minus -9 the second set
