All about Multiplying by 10, 100 and 1000
When you multiply a whole number by 10, every digit moves one place to the left and a zero is added at the end.
For example, 6 × 10 = 60, 6 × 100 = 600 and 6 × 1000 = 6,000. These patterns work because our number system is based on powers of ten. The pattern is also useful when converting between metres, centimetres and millimetres.
