NCERT Solutions for Class 6 Maths Chapter 2: Whole Numbers

This chapter demystifies the concepts of natural numbers, number line, whole number and properties of whole numbers. By the end of this chapter, students will be acquainted with the concepts of Closure property, Commutativity of addition and multiplication, Associativity of addition and multiplication, Patterns in Whole Numbers and Distributivity of multiplication over addition. This chapter also introduces young minds to pattern formations. It is essential to understand the meaning and the difference between natural numbers and whole numbers for better understanding of integers and other complex concepts. Understanding number line helps in the chapter of algebra where students have to use the properties learnt in this chapter to variables along with the numbers. This chapter not only helps students improve their calculation speed but also increase their cognitive skills. Let us briefly discuss what this chapter is about:

• Natural numbers
  The numbers that can be counted are called natural numbers.
• Number line
  The representation of the numbers on a line having equidistant numbers for calculation is called a number line.
• Whole Numbers
  When Zero is included in the list of natural numbers, it forms the concept of whole numbers.
• Properties of whole numbers
  Commutativity, associativity and distributivity properties of whole numbers are useful in simplifying calculations.
• Pattern formation
  Pattern formation is useful, especially for verbal calculations and helps us to understand the properties of numbers better.
