Question

Solve using properties.
i) $(- 5) \times (- 8) \times (- 2) \times (5)$
ii) $74 \times (- 101)$
iii) $36 \times 4 - (- 36) \times 6$
iv) $(- 8 + 0) + (31 - 1) - (0 \div 45)$

Open in App

Solution

$i) (- 5) \times (- 8) \times (- 2) \times (5)$
$= (40) \times (- 10) = (- 400)$

$i i) (74) \times (- 101) = (- 7474)$

$i i i) 36 \times 4 - (- 36) \times 6$
$= (144) - (- 216) = (144 + 216) = 360$

$i v) (- 8 + 0) + (31 - 1) - (\frac{0}{45})$
$= (- 8) + (30) - 0 = 22$
