The whole numbers are a member of the number system. These numbers are similar to the natural numbers, except that they begin from zero instead of one, and they go all the way to infinity. In this chapter of the RS Aggarwal Class 6 Maths book will learn about the whole numbers primarily. The concept of whole numbers dates back to the ancient Indian civilisation around the 5th century AD, and the first use of numeral zero originated with the Indian mathematician Brahmagupta.
This chapter deals with the theory of whole numbers and natural numbers. Predecessors and successors are also discussed with numerical problems for you to solve. The predecessor is the number you achieve by subtracting 1 to the given number, and if you add 1, you get the successor. You will also be learning how to draw a number line and perform various operations on it, like addition and subtraction, by marking values on the number line itself. The properties of whole numbers like closure, commutative, and associative are also discussed thoroughly with numerous examples and brief notes. Questions based on these properties are there in the exercises, and this needs your practice to grasp the chapter to the fullest. Fundamental topics like these are important in the long journey of high school mathematics.
The exercises constitute fundamental problems, and thus you need to be properly guided with well explanatory comments with no-step-skipped solutions. RS Aggarwal Solutions for Class 6 Maths bring you the luxury of having easy solutions to the questions with theory for your better comprehension.
