2. What are Real numbers
Real numbers can be defined as the union of both rational and irrational
numbers. They can be both positive or negative and are denoted by the
symbol “R”. All the natural numbers, decimals and fractions come under this
category.

4. Rational Numbers
Rational number, in arithmetic, a number that can be
represented as the quotient p/q of two integers such that q ≠
0. In addition to all the fractions, the set of rational numbers
includes all the integers, each of which can be written as a
quotient with the integer as the numerator and 1 as the
denominator.
5. Integers
An integer is a whole number (not a fractional number) that can
be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8,
97, and 3,043. Examples of numbers that are not integers are: -
1.43, 1 3/4, 3.14, .09, and 5,643.1.
6. Natural Numbers
Natural numbers are a part of the number system which includes all the positive integers
from 1 till infinity and are also used for counting purpose. It does not include zero (0). In
fact, 1,2,3,4,5,6,7,8,9…., are also called counting numbers.Natural numbers are denoted by
“N”.
7. Whole Numbers
The whole numbers are the numbers without fractions and it is a collection of
positive integers and zero. It is represented by the symbol “W” and the set of
numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing
or a null value. Whole Numbers: W = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10……}
8. Irrational Numbers
Irrational number, any real number that cannot be expressed as the
quotient of two integers—that is, p/q, where p and q are both
integers. For example, there is no number among integers and
fractions that equals Square root of√2.
9. Addition Rule
When the signs on the two terms are same then we should add and
keep the sign in front of the large number.
Eg: (-4) + (-7) = 11
(-4) + (-7)= -11
