Class 6 Mathematics
Chapter 6: Integers
STAGE 0: Foundation
In daily life, we see numbers below zero 😊
Examples:
- Temperature below 0°C
- Basement floors in buildings
- Loss in business
Such numbers are called integers.
STAGE 1: Concepts Explained
What are Integers?
Integers are numbers that include:
- Positive numbers
- Negative numbers
- Zero
Examples:
…, −3, −2, −1, 0, 1, 2, 3, …
Positive Integers
Numbers greater than zero are positive integers.
Examples: 1, 2, 3, 4
Negative Integers
Numbers less than zero are negative integers.
Examples: −1, −2, −3, −4
Zero
Zero is neither positive nor negative.
Number Line
Integers are shown on a number line.
- Zero is at the centre
- Positive numbers are on the right
- Negative numbers are on the left
STAGE 2: Operations on Integers
Addition of Integers
Addition of integers can be understood using a number line.
Example:
(+3) + (−5)
Solution:
Start from 3, move 5 steps left.
Answer = −2
Subtraction of Integers
Subtraction means adding the opposite number.
Example:
5 − (−3)
Solution:
5 − (−3) = 5 + 3 = 8
STAGE 3: Practice Questions
1. Write any three negative integers.
2. Which is greater: −2 or −5?
3. Find: (−4) + 6
4. Find: 7 − (−2)
5. Show −3 on a number line.
STAGE 4: Quick Revision
- Integers include negative numbers, zero, and positive numbers
- Zero is neither positive nor negative
- Positive numbers lie to the right of zero
- Negative numbers lie to the left of zero
- Number line helps understand operations
