Solve Multiplication Problems

When we have to work out lots of repeated additions of the same amount, it is much easier to multiply.

Example

A dog has 4 legs.

How many legs will 12 dogs have?

Answer

We need to work out 12 lots of 4 

which is quicker than adding 4 + 4 + 4 + 4 + 4 + ... etc. twelve times.

This is 12 x 4   

12 x 4 = 48

12 dogs will have 48 legs. 

Though the one below might mess up that calculation since he has only three legs!

Let's have a go at some questions now.
