Comparing Integers
Learn how to determine which integer is greater or smaller using the number line and simple rules!
1. The Number Line Method
The Golden Rule
On a number line:
- Right = Greater (bigger numbers are to the right)
- Left = Smaller (smaller numbers are to the left)
This visual method works for any integers — positive, negative, or zero!
Example: Compare −2 and −5
On the number line, −2 is to the RIGHT of −5
Therefore: −2 > −5

2. Basic Comparison Rules
Positive vs Zero
Any positive > 0
Examples: 1 > 0, 100 > 0
Negative vs Zero
Any negative < 0
Examples: −1 < 0, −100 < 0
Positive vs Negative
Any positive > Any negative
Example: 1 > −1000
Remember the Chain:
Negative < 0 < Positive
Example: −100 < −1 < 0 < 1 < 100
