Multiply numbers ending in zeroes

When you multiply two numbers with any of them having ending zeroes, you can do this:

**Step 1. ** |
Count the number of zeroes that are there at the end of both numbers. Say there are 3 all together. |

**Step 2.** |
Remove them from both numbers. |

**Step 3.** |
Look at the remaining two numbers. |

**Step 4.** |
Multiply those numbers |

**Step 5.** |
Now put back the combined number of removed zeroes at the end of the answer in step 4 |

Take the following multiplication
20x700

Now let's see how each of the above steps apply

- Count the number of zeroes that are there at the end of both numbers.
**3 all together** One in 20 and two in 700. Together they make three.
- Remove them from both numbers.
**2 x 7**
- Look at the remaining two numbers.
**2 and 7 **
- Multiply those numbers
**2 x 7 = 14**
- Now put back the combined number of removed zeroes at the end of the answer in step 4.
**14000**. See how the 3 zeroes are added to 14 making 14,000.
