About the numbers 1 to 10 and 0
|101||One hundred and one ...||101|
|In figures||In words||Pronounce It|
|101st||the hundred and first||...|
Ordinal numbers are often used in fractions:-
|Symbols||Word (common term in brackets)||Pronounce It|
|-||Minus (Take away)||-|
|x||Multiplied by (Times)||x|
|(((1 + 6) - 2) x 2) ÷ 2.5=4||
One plus six minus two multiplied by two divided
by two point five equals four
|1 + 6 - 2 x 2 ÷ 2.5=4|
|10% 100=10||Ten percent of one hundred equals ten.||10% 100=10|
Not all numbers are whole numbers, or just fractions (see above), they are a mixture of both.
When pronouncing decimals we use the word
point to represent the dot. The numbers following the dot are pronounced
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.
|When we use it||For example:-|
|0 = oh||after a decimal point||9.02 = "Nine point oh two."|
|in bus or room numbers||Rooom 101 = "Room one oh one."
Bus 602 = "Bus six oh two."
|in phone numbers||9130472 = "Nine one three oh four seven two."|
|in years||1906 = "Nineteen oh six."|
|0 = nought||before a decimal point||0.06 = "Nought point oh six."|
|0 = zero||in temperature||-10°C = "10 degrees below zero."|
|US English for the number||0 = "Zero"|
|0 = nil||in football||Chelsea 2 Manchester United 0 = "Chelsea two Manchester United nil."|
|0 = love||in tennis||20 - 0 = "Twenty love."|
~ 12 ~
~ 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.
~ k ~
The letter k is often used to denote a thousand. So, 1k = 1,000.
If you see a job advertised and it offers a salary of £12k it means £12,000.00.
~ m ~
The letter m is often used to denote a million. So, 1m = 1,000,000.
If you see a job advertised and it offers a salary of £12m, apply for it!
~ bn ~
The letters bn denote a billion. So, 1bn is usually 1,000,000,000 (see above).
If you see a job advertised and it offers a salary of £12bn, it's probably a missprint.
The word myriad used to mean 10,000. Nowadays it's used to refer to a countless number or multitude of specified things.
For example: Earth hosts a myriad of animals.
