Solution

(i) (–2) × 3 × (–4)
= [(–2) × 3] × (–4)
= (–6) × (–4)
= 24

(ii) 2 × (–5) × (–6)
= [2 × (–5)] × (–6)
= (–10) × (–6)
= 60

(iii) (–8) × 3 × 5
= [(–8) × 3] × 5
= (–24) × 5
= –120
(iv) 8 × 7 × (–10)
= [8 × 7] × (–10)
= 56 × (–10)
= –560
(v) (–3) × (–7) × (–6)
= [(–3) × (–7)] × (–6)
= 21 × (–6)
= –126
(vi) (–8) × (–3) × (–9)
= [(–8) × (–3)] × (–9)
= 24 × (–9)
= –216
