Students began their 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, .... the number system was thus extended, from natural numbers to whole numbers and from whole numbers to integers.
Students were also introduced to fractions in previous classes. These are numbers of the form numerator and denominator, where the numerator is either 0 or a positive integer and the denominator, a positive integer. Students compared two fractions, found their equivalent forms and studied all the four basic operations of addition, subtraction, multiplication and division on them. In NCERT Grade 7 Chapter 9, Rational Numbers students shall extend the number system further.
