Question: work out −0.3 × (−0.2).

−0.3 × (−0.2)

3 × 2 = 6

1 + 1 = 2 digits after the point → 0.06

Minus times minus is plus.

Forget the points: 3 times 2 is 6.

Together, the numbers have 1 + 1 = 2 digits after the point.

So the answer has 2 too: 0.06.

= 0.06

So the answer is 0.06.

Answer

= 0.06

Try this one yourself, then check:
