Answer:
2) Subtract: (i) -244 (ii) -96
3) Verify the following: (a) 48 = 48, TRUE (b) 230 = 230, TRUE
Explanation:
2) Subtract:
(i) 119 from -125
= -125 - 119
= -244
(ii) -214 from -310
= -310 - (-214)
= -310 + 214
= -96
3) Verify the following:
a. 16 [7 + (-4)] = [16 × 7] + [16 × (-4)]
= 16 [7 -4] = [112] + [16 × -4]
= 16 [3] = [112] + [-64]
= 48 = 112 - 64
= 48 = 48
This is true because both sides are equal.
b. -23 × [(-8) + (-2)] = [(-23) × (-8)] + [(-23) × (-2)]
= -23 × [-8 - 2] = [-23 × -8] + [-23 × -2]
= -23 × [-10] = [184] + [46]
= -23 × -10 = 184 + 46
= 230 = 230
This is true because both sides are equal.
