Here are some tips for multiplying in your head.

Try

**7 x 6**

Use your knowlege of times tables to recall the multiplication fact for 7 x 6 to get the answer 42.**12 x 7**

Remember that 12 is 2 x 6, so 12 x 7 can also be expressed as:

2 x 6 x 7

(12) x 7

Recall from your times tables that 6 x 7 = 42

So times 42 by the remaining 2 to get the answer: 42 x 2 =**84****35 x 8**

Because 8 is 2 x 2 x 2, when you work out 35 x 8, you can do it like this:

35 x 2 x 2 x 2

= 70 x 2 x 2

= 140 x 2**= 280**To multiply a number by 10, move the digits one place to the left, adding a zero if necessary.

58 x 10 =

**580**To multiply a number by 100, move the digits two places to the left, adding zeros if necessary.

58 x 100 =

**5800**To multiply by numbers such as 20 or 300, multiply by the 2 or 3 first and then by the 10 or 100.

33 x 20

= 33 x 2 x 10

= 66 x 10

=**660**22 x 300

= 22 x 3 x 100

= 66 x 100

=**6600**
