This is the base of the Mathematics. First of all we want to know about the number system.In this part we can expect a question from Prime Number.
Natural Number
Number used for counting is a called Natural Number
Whole Number
All natural numbers including zero is called whole numbers
Even and Odd Numbers
Numbers divisible by 2 are called Even Numbers.Otherwise it is called Odd numbers.
Integers
The set of all negative numbers and whole numbers is known as integers.
...-4,-3,-2,-1,0,1,2,3...
Rational Numbers
Numbers of the form p/q, q not equal to zero is called Rational numbers.
Irrational Numbers
The numbers which are non repeating and non terminating is called irrational Numbers e.g √2 π √5
Real Numbers
The set of all rational Numbers and irrational Numbers is known as real Numbers
Prime Numbers
The numbers which has only two factors 1 and itself is called Prime numbers.
E.g 2,3,5,7....
