Question

2 Evaluate the following.
(a) 12 = [(13) + (-13)]
(b) [(56) + (-2)] + (-4)
(C) [(-100) + (60)] = [(29) - (9)]
(d) (-6) - [(36) - (-12)]​

Answer 1

Answer:

a)12=[(13)+(-13)]

12=[13-13]

12=0

b)[(56)+(-2)]+(-4)

56-2+4

56+2

58

c)[(-100)+(60)]=[(29)-(9)]

-40=20

-40-20=0

-60=0

d)(-6)-[(36)-(-12)]

-6-36+12

-42+12

-30
