Times tables knowledge.

You will find many calculations easier if you are able to recall your times tables - multiplication facts up to 10 x 10

If you do not know the answer there is always a way to work it out.

A common way of working out an answer is to add a number over and over until you have added it the required number of times for the calculation.

A property of multiplication is that the order does not matter!

So this addition can be carried out on either number, enabling you to repeatedly add the number you find the easiest to work with from the calcualtion.

So if you need to calculate 6 x 7 this can be worked out by doing either of the repeated additions

Adding the 6's, 6 + 6 + 6 + 6 + 6 + 6 + 6 which would give the numbers as you add on 6, 12, 18, 24, 30, 36, 42 so the answer is 42

Adding the 7's, 7 + 7 + 7 + 7 + 7 + 7 which gives 7, 14, 21, 28, 35, 42 so the answer is 42

The key with learning these is to do them often. The more you test yourself the quicker you will become at answering them and then ultimately you wil be able to recall them without needing to carry out a calcuation.
