Question

If a=-9 and b =-6, show that (a - b)+10-a).
3. If a=-8, b=-7,c=6, verify that (a + b)+c=a +(b+c) ​

Answer 1

Answer:

given,

a= -9 and b= -6

(a-b)+10-a

=-9-(-6)+10-(-9)

=-9+6+10+9

=16

2.

given

a=-8 b= -7 and c=6

then

(a+b)+c= a+(b+c)

-8-7+6=-8+(-7+6)

-15+6=-8-1

-9=-9

hence verified
