Question

Find the product, using suitable properties:
$(-17)\times (-29)$
(2 marks)

Answer 1

Given expression:
(-17) × (-29)
We can split up -29 into (-30 + 1) in order to simplify the calculation.

= (-17) × (-29)
= (-17) × (-30 + 1)
= [(-17) × (-30) + (-17) × 1]
...(By applying distributive property) (1 mark)

= 510 - 17
= 493 (1 mark)
