WHAT TO SAY

ONE

We often say “a” instead of “one”.
For example when we have the numbers 100 or 1/2 we say “A hundred” or “A half”.

FRACTIONS

Not all numbers are whole numbers, or just fractions (see above), they are a mixture of both.

For example:
11/2 – “One and a half.”

DECIMALS

When 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 OF

Square 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.

INTERESTING NUMBERS

~ 0 ~

What could possibly be interesting about nothing?

Try writing the numbers zero ( 0 ) through nine ( 9 ).

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.

When we use itFor example:-
0 = ohafter a decimal point9.02 = “Nine point oh two.”
in bus or room numbersRooom 101 = “Room one oh one.”
Bus 602 = “Bus six oh two.”
in phone numbers9130472 = “Nine one three oh four seven two.”
in years1906 = “Nineteen oh six.”
0 = noughtbefore a decimal point0.06 = “Nought point oh six.”
0 = zeroin temperature-10°C = “10 degrees below zero.”
US English for the number0 = “Zero”
0 = nilin footballChelsea 2 Manchester United 0 = “Chelsea two Manchester United nil.”
0 = lovein tennis20 – 0 = “Twenty love.”

~ 12 ~

The number 12 is often represented as a dozen and the number 6 as a half dozen.

For example:
12 eggs= “A dozen eggs.”
6 eggs = “Half a dozen eggs.”

~ 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 centum.

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 billion traditionally means a million million = 1,000,000,000,000 = 1012

In American English billion means a thousand million = 1,000,000,000 = 109

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 109 and “million million” for 1012.

Milliard ” is French for the number 109. It is not used in American English but is sometimes, but rarely, used in British English.
