# Square root

## Square root – The square root of a number is the value that is multiplied by itself to give you that number.

## (i.e. the root of the number)

The square root has a symbol that is shaped like a tick.

To help you remember what the square root of a number is think of a **ROOT** OF A TREE covered in ticks (bugs) (see below).

**Examples**

What is the square root of 9?

We know the tree is 9 but what is its ROOT?

The root of 9 is 3 `(3times3=9)`

**NOTE:**

The square root has a symbol, a sort of tick with a line.

`root()9=3`

We say the square root of 9 equals 3.

Here are the first 10 square roots of numbers up to 100:

`root()1` |
`=` |
`1` |

`root()4` |
`=` |
`2` |

`root()9` |
`=` |
`3` |

`root()16` |
`=` |
`4` |

`root()25` |
`=` |
`5` |

`root()36` |
`=` |
`6` |

`root()49` |
`=` |
`7` |

`root()64` |
`=` |
`8` |

`root()81` |
`=` |
`9` |

`root()100` |
`=` |
`10` |

NOTE:

These should be easy because if you see the section on multiplication tables it is imperative that a child should know all numbers up to 12 multiplied by themselves.
