Question

Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)

Answer 1

Step-by-step explanation:

Given:

a = (-12)

b = 4

c = (-25)

Solution:

LHS=a+(b+c)

=(-12)+{4+(-25)}

=(-12)+(4-25)

=(-12)+(-21)

=(-12-21)

=-33

RHS=(a+b) +c

={(-12)+4}+(-25)

=(-12+4)-25

=(-8-25)

=-33

LHS=RHS
