Solution
5 × [(–3) × 6]
= 5 × (–18) (Solving multiplication in square brackets first)
The magnitude of (–18) is 18.
So, the product of the magnitudes is 90.
Now, we know that the product of a negative and a positive integer is always negative.
∴ 5 × [(–3) × 6] = –90
= 5 × (–18) (Solving multiplication in square brackets first)
