- Introduction: The numbers are the foundation of mathematics and we use different kinds of numbers in our daily life. So it is necessary to be familiar with various kinds of numbers In this unit we shall discuss real numbers and complex numbers including their properties. There is a one-one correspondence between real numbers and the points on the real line. The basic operations of addition, subtraction, multiplication and division on complex numbers will also be discussed in this unit.
- Real Numbers: We recall the following sets before giving the concept of real numbers.
- Natural Numbers: The numbers 1, 2, 3, ... which we use for counting certai are called natural numbers or positive integers. The set of natural numbers is denoted by N. i.e., N = { 1, 2, 3, ....... }
- Whole Numbers: If we include 0 in the set of natural numbers, the resulting the set of whole numbers, denoted by W, i.e., W = { 0, 1, 2, 3, ....... }
- Integers: The set of integers consist of positive integers, 0 and negative integersand is denoted by Z i.e., Z = { ..., – 3, – 2, – 1, 0, 1, 2, 3, ... }
- Set of Real Numbers: First we recall about the set of rational and irrational numbers.
- Rational Numbers: All numbers of the form p/q where p, q are integers and q is not zero are called rational numbers. The set of rational numbers is denoted by Q, i.e., Q = { p / q l p , q E Z ^ q ≠ 0 }
- Irrational Numbers: The numbers which cannot be expressed as quotient of integers are called irrational numbers. The set of irrational numbers is denote denoted by Q', Q' = { x l x ≠ p / q , p , q E Z ^ q ≠ 0 }
