Question 52 Marks
State which is greater:
(8 - 9) × 10 and 8 - 9 × 10
Answer
⇒ (8 - 9) × 10 = -1 × 10
⇒ (8 - 9) × 10 = -10
⇒ 8 - 9 × 10 = 8 - 90 = -82
(8 - 9) × 10 > 8 - 9 × 10

Question 72 Marks
State which is greater:
{(-2) - 5} × (-6) and (-2) - 5 × (-6)
Answer
((-2) - 5) × -6
= (-7) × (-6)
= (7 × 6)
= 42
(-2) - 5 × (-6)
= -2 + (5 × 6)
= 30 - 2
= 28
Therefore, ((-2) - 5×(-6)) > (-2) - 5 × (-6)

Question 192 Marks
Verify the following:
19 × {7 + (-3)} = 19 × 7 + 19 × (-3)
Answer
L.H.S = 19 × (7+ (-3))

= 19 × 4
= 76
R.H.S = 19 × 7 + 19 × (-3)
= 133 - 57
= 76
Therefore, L.H.S = R.H.S
