What Are Whole Numbers? Whole numbers are the numbers we use when we count things. They are numbers that:
Start from zero (0)
Go up by one each time (1, 2, 3, 4…)
Do not have decimals or fractions
They are not negative (no minus signs)
Examples of Whole Numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...
Why Are They Called “Whole”? They’re called “whole” because they represent complete things.
You can't have half a person or 1.3 chairs—you count whole people or whole chairs.
Where Do You Use Whole Numbers in Real Life?
Whole numbers are everywhere:
👩🍳 Cooking: “Add 3 eggs.”
🛍️ Shopping: “That costs $25.”
🧍 Counting people: “There are 4 people in line.”
🕒 Time: “I’ll meet you in 2 hours.”

🌟 Simple Tricks to Remember:
