Answer 2

Qᴜᴇsᴛɪᴏɴ:

• Find the product by convenient grouping.

Sᴏʟᴜᴛɪᴏɴ:

(i) 8 × 43 × (-125)

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf [8×(-125)] × 43$

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf -1000 × 43$

$~~~~~~~~~$ $\sf \dashrightarrow$ ${\boxed{\sf{-43,000}}}$

(ii) (-2) × 18 × (-50)

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf [(-2) × (-50)] × 18$

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf 100 × 18$

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf 1,800$

(iii) (-16) × 25 × (-4) × (-2)

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf [25 × (-4)] × [-16 × (-2)]$

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf -100 × 32$

$~~~~~~~~~$ $\sf \dashrightarrow$ $\sf -3,200$
