When we multiply two numbers together, the two numbers being multiplied can be done in either order, and still give the same answer. This is known as 'cumulative property'. For example, 5 x 4 gives the same result as 4 x 5. This knowledge can be used to answer any questions involving times tables children are unfamiliar with (if they don't know 5 x 7, they may know 7 x 5 for instance). Cumulative property also applies when 3, 4 or any other group of numbers are to be multiplied. The calculation can be done in any order and the answer will be the same.

Try this quiz to see how much you know about multiplying in any order.

1.

Which number is missing?

? x 8 = 16

? x 8 = 16

4

24

12

2

If you know that 8 x 2 = 16, then 2 x 8 = 16 also

2.

When you multiply two numbers...

you can multiply them in any order

you should add them first

you will get an answer of more than 50

you will also find the difference

When multiplying two numbers, it doesn't matter which way round they go, you will still get the same answer

3.

Which of the following pairs give an answer of 60?

60 x 2 and 2 x 60

30 x 2 and 2 x 30

15 x 3 and 3 x 15

40 x 4 and 4 x 40

2 x 30 gives an answer of 60, as does 30 x 2

4.

What is 50 x 2?

52

100

25

70

2 x 50 is much easier to work out!

5.

Which number is missing?

20 x ? = 80

20 x ? = 80

60

40

24

4

4 x 20 = 80 and 20 x 4 = 80 too

6.

What could make this calculation easier to work out?

5 x 12

5 x 12

Quickly learning the 12 times table

Adding the two numbers together

Changing the numbers around to 12 x 5

Finding the difference between the two numbers

5 x 12 = 60 and 12 x 5 also gives the same answer

7.

What is 100 x 4?

410

40

104

400

Changing the order of the numbers makes this 4 x 100, which is easier to work out

8.

I don't know my 7 times table yet. How could I work out 5 x 7?

By quickly learning the 7 times table

By doing 7 x 5 instead

By guessing the answer

By adding 7 and 5 together

5 x 7 = 35 and 7 x 5 is 35 too

9.

Which of the following pairs give an answer of 20?

20 x 2 and 2 x 20

4 x 5 and 5 x 4

10 x 4 and 4 x 10

10 x 20 and 20 x 10

4 x 5 = 20, as does 5 x 4

10.

5 x 6 gives the same answer as...

40 x 5

4 x 50

5 + 4

6 x 5

They both give an answer of 30
