Tips to Remember the Difference
Here are some simple memory tricks to remember greater than or less than.
1. The Hungry Alligator Trick
Imagine the symbol is a hungry alligator.
The alligator always eats the bigger number.
Example:
8 > 3
The open mouth faces 8 because it is larger.
2. Open Side = Bigger Number
The open side of the symbol always points toward the bigger number.
Example:
9 > 2
The open side faces 9.
3. Pointed Side = Smaller Number
The pointed tip of the symbol points toward the smaller number.
Example:
4 < 10
The tip points toward 4.

Use Less Than ( < ) When:
- One number is smaller than another
- Comparing small quantities
- Showing lower values
- Describing limits or conditions
Examples:
- 5 < 12
- 30 < 50
- 10 < 20
