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 it
|
For
example:-
|
||
|
0 =
oh
|
after a decimal
point
|
9.02 = "Nine point oh two."
|
||
|
|
in bus or room
|
Rooom 101 = "Room one oh one."
|
||
|
|
numbers
|
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 ~
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.
|
||
|
LETTERS AS NUMBERS
|
||
|
~ 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.
|
||
|
myriad
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.
