BACK TO WORKSHEETS
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.
