Answer:

2) (i) 224 (ii) -524

3 a and b are correct

Answer:

2) Subtract: (i) -244 (ii) -96

3) Verify the following: (a) 48 = 48, TRUE (b) 230 = 230, TRUE

Step-by-step 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.
