## Multiplying by tens, hundreds and thousands

To times by ten you add a '0' from the 10 to the number your are multiplying it by to get the answer.

5 x 10 = 50

To times by one hundred you add two '0' from the 100 to the number you are multiplying it by to get the answer.

3 x 100 = 300

To times by one thousand you add three '0' from the 1000 to the number you are multiplying it by to get the answer.

6 x 1000 = 6000

You can now work out any sum which is multiplied by 10, 100 or 1000.

56 x 100 = 5600

Here you just at two '0' from the 100 to 56 to get the correct answer.

## Multiplying by the grid method

To work out 45 x 5 break the 2-digit number up and multiply by them by the other number.

40 x 5 = 200

2 x 5 = 10

Add the answers together.

200 + 10 = 210

So

42 x 5 = 210

If you have a bigger numbers split them into a table to work out the answer. Try 52 x 13.

x | 50 | 2 |

10 | 500 | 20 |

3 | 150 | 6 |

Now add the columns together

x | 50 | 2 |

10 | 500 | 20 |

3 | 150 | 6 |

650 | 26 |

Now add up the two number in red.

650 + 26 = 676

So

52 x 13 = 676
