Natural numbers: - When we begin to count 1, 2,
3, 4, 5, 6, 7, ....to infinity etc
numbers comes naturally before us hence, mathematicians call the counting
numbers as Natural numbers.
Collection of Natural Numbers is
denoted by Capital N.
N = { 1, 2, 3, 4, 5, 6, 7, ………
}

Whole Numbers: - The natural numbers along with
zero form the collection of whole numbers i.e. 0, 1, 2, 3, 4, 5, 6, 7, ....
Collection of Whole Numbers is
denoted by Capital W.
W = { 0, 1, 2, 3, 4, 5, 6, 7, ………}

Integer:
- The set of
Negative and Positive whole numbers including zero is called Integer. Collection of Integers is denoted
by Capital Z.
Z = {– , ..….., – 3, – 2,
– 1, 0, + 1, + 2 +3, ………, +}

There
are two types of integer number.
01.
Negative integer: - The integer with Negative sign and started from – to – 1is called
Negative Integers i.e. – , ..….., – 3, – 2, –
1
02.
Zero: -
Integer 0 is neither negative nor positive.
03.
Positive integer: - The integer with positive number started from 1 to is called Positive Integers i.e. + 1, + 2, + 3, ……, +
Rational
Number: - The
number in the form of p/q is called Rational number where q ≠ 0 and p and q are
integer.
There are two types of
rational number.
01.
Negative Rational Number: - A rational number is said to be Negative if either
its Numerator or Denominator is Negative.
, 
, 
, 
, 
, 
,are Negative Rational Numbrs
02.
Zero Rational Number: - 0 is a rational Number
because it can be written in the form of 
with non zero q ≠ 0.
03.
Positive Rational Number: - A rational number is said to be positive if its
Numerator and Denominator both are Negative or Positive.
, 
, 2, 91, 
, 
are Positive
Note
that: - 
(Division by 0 is not define) and 
There are two types of
Rational Numbers.
01.
Terminating and 02. Non
terminating number
01.
Terminating Rational Numbers: - Which number divided completely by denominator is
called Terminating Rational Number. As 
, 
, 
, 
etc.
02.
Non-Terminating Number: - In which rational numbers, the division process never does not comes to
end are called Non-Terminating Number.
These
are of two types
a)
Non-Terminating Repeating Numbers and
b)
Non-Terminating Repeating Non Repeating
a)
Non-Terminating Repeating Numbers or Non Terminating Recurring Numbers: - In which Non terminating
numbers in the division process reminder starts repeating after a certain
numbers are called Non Terminating Repeating Numbers or Non Terminating
Recurring Numbers.
These
Repeating Numbers are represented by putting a bar over the first block or
group or pair and other repeating parts of number will omit after putting a
Bar.
When
reminder repeats itself then you should understand that the quotient repeats
itself.
b)
Non-Terminating and Non Repeating Numbers: - In which Non terminating numbers, in the
division process reminder starts repeating after a certain numbers are called
Non Terminating and Non Repeating Numbers.
Irrational
Number: - The
real numbers that are not expressible in the form of p/q is called Irrational
number where q ≠ 0 and p and q are integer.
Pi is an irrational number.
