10% 100=10 | Ten percent of one hundred equals ten. | 10% 100=10 |

## WHAT TO SAY |
---|

## ONEWe often say “a” instead of “one”. ## FRACTIONSNot all numbers are whole numbers, or just fractions (see above), they are a mixture of both. For example: |

## DECIMALSWhen pronouncing decimals we use the word “point” to represent the dot. The numbers following the dot are pronounced separately. For example: When you have the number 1.36 we say “One point three six.” |

## SQUARED / CUBED / TO THE POWER OFSquare numbers are written 2² = we say “Two squared” = 2 x 2 = Two squared equals four. Cubed numbers are written 2³ = We say “Two cubed” = 2 x 2 x 2 = Two cubed equals eight You can also say “to the power of” – “Two to the power of two equals four.” and “Two to the power of three equals eight.” You can then have “to the power of” any number. Two to the power of twelve = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 4096. It’s much easier to write 2¹² = 4096. |

## ~ 0 ~What could possibly be interesting about nothing?
0 1 2 3 4 5 6 7 8 9 Then write how many numbers you have counted:- 1 2 3 4 5 6 7 8 9 10 Yes, ten numbers, without using the number 10. You can put as many noughts in front of a number without changing the value of that number:- 01, 002, 0003, 00004 … In English 10, 20, 30, through to 90 are 1 ten, 2 tens, 3 tens, etc. Also there are a number of ways you can say 0 in English.

## ~ 12 ~The number 12 is often represented as a dozen and the number 6 as a half dozen. For example: | ||||||||||||||||||||||||||||||

## ~ 13 ~A dozen is 12, but a baker’s dozen is 13, because in the past bakers who were caught shortchanging customers could be liable to severe punishment, so they used to add an extra bread roll to make up the weight. | ||||||||||||||||||||||||||||||

## ~ 100 ~A century is 100. The roman numeral for 100 is C, for One hundred is the basis of percentages (literally “per hundred”). 100% is the full amount of something. | ||||||||||||||||||||||||||||||

## *~ 1 billion ~When is a billion not a billion? In British English In American English The American billion has become standard in technical and financial use. However, to avoid confusion it is better to use the terms “thousand million” for 10
^{9}. It is not used in American English but is sometimes, but rarely, used in British English. |
