Question

3. Verify the following:
(0) [(-2)+(-9)] + 6 = (-2)+[(-9)+6] (n) {7+(+8)]+(-5) = 7+[(-8) +(-5),
(m) [(-11)45]+(-14) = (-11)+ [5+(-14)]
(iv) (-5)+[(-32) +(-2)]=[(-5)+(-32)]+(-2)​

Answer 1

Answer:

o)-2-9 + 6 = -2-9+6

-11+6 = -11 + 6

n)7+8 -5 = 7+ (-8 -5)

15 -5 = 7 - 13

15 -7 = 5 - 13

8 = 8

m) 34 - 14 = -11 + 5 -14

20 = -11 - 9

20 = 20

iv)-5-32-2 = -5 -32 -2

-39 = -39
