9.1 INTRODUCTION
You began your study of numbers by counting objects around you.
The numbers used for this purpose were called counting numbers or
natural numbers. They are 1, 2, 3, 4, ... By including 0 to natural
numbers, we got the whole numbers, i.e., 0, 1, 2, 3, ... The negatives
of natural numbers were then put together with whole numbers to make
up integers. Integers are .... -3, -2, -1,0, 1, 2, 3, .... We, thus, extended

the number system, from natural numbers to whole numbers and from
whole numbers to integers.
You were also introduced to fractions. These are numbers of the form
denominator
where the numerator is either 0 or a positive integer and the denominator, a positive integer.
You compared two fractions, found their equivalent forms and studied all the four basic
operations of addition, subtraction, multiplication and division on them.
In this Chapter, we shall extend the number system further. We shall introduce the concept
of rational numbers alongwith their addition, subtraction, multiplication and division operations.
