Answer:
Answer:
(i) a = 21, b = 18
a – (-b) = 21-(-18)
21-(-18) = 21 + 18
21+18= 39
a + b = 21+18
21+18 = 39
21-(-18) = 21+18 = 39
(ii) a = 118, b = 125
a – (-b) = 118 – (- 125)
118- (- 125) = 118 + 125 = 243
a + b = 118 + 125
118 + 125 = 243
118 – (- 125) = 118 + 125 = 243
(iii) a = 75, b = 84
a – (-b) = 75 – (- 84)
75 – (- 84) = 75 + 84 =159
a + b = 75 + 84
75 + 84 =159
75 – (- 84) = 75 + 84 =159
(iv) a = 28, b = 11
a – (-b) = 28 – (-11)
28 – (-11) = 28 + 11 = 39
a + b = 28 + 11= 39
28 +11= 39
28 – (-11) = 28 +11= 39
