How to Solve Whole Numbers — Step by Step Guide

Properties of whole numbers, number line, and patterns. This guide covers Class 6 to 6.

Step-by-Step Method

1
Whole numbers are 0, 1, 2, 3, ... They include 0 but not negative numbers or fractions.
2
Closure property: whole numbers are closed under addition and multiplication.
3
Commutative property: a + b = b + a and a × b = b × a.
4
Associative property: (a + b) + c = a + (b + c).
5
Distributive property: a × (b + c) = a × b + a × c.

Worked Example

Problem: Verify the distributive property for 7 × (20 + 3).

Solution: 7 × 23 = 161. Also, 7 × 20 + 7 × 3 = 140 + 21 = 161. Both sides are equal.

Common Mistakes to Avoid

✗
Including negative numbers in whole numbers — whole numbers start from 0.
✗
Saying whole numbers are closed under subtraction (5 - 8 = -3 is not a whole number).
✗
Confusing natural numbers (from 1) with whole numbers (from 0).
✗
Not recognising 0 as the identity element for addition and 1 for multiplication.
