Question: work out −2 × (−3) × (−1).

−2 × (−3) × (−1)

Times and divide: we go from left to right.

same kind: left → right

− × − = +

Minus times minus is plus.

2 times 3 is 6.

So we get 6.

= 6 × (−1)

+ × − = −

Plus times minus is minus.

6 times 1 is 6.

So we get −6.

= −6

So the answer is −6.

Answer

= −6

Try this one yourself, then check:

Work out −2 × (−5) × (−1)
