Maths Learn By Heart - multiplying and dividing by 10, 100 or 1000

We have a new LBH task now and again it focusus on the basic skills that you will need for the rest of your lives. There are some simple tricks, however, to make these problems a little less daunting...

Divide by 10 = move the decimal point 1 place to the left (so 50.0 becomes 5.0)
Divide by 100, move it 2 places to the left.
Divide by 1000, move it 3 places to the left.

To multiply by 10, simply move the decimal point 1 place to the RIGHT (so 10.0 becomes 100.0)
To multiply by 100, move it 2 places to the right.
To multiply by 1000, move it 3 places to the right.

If you need any help then please just ask - and be ready for our tests on the following dates;
