Inequality notation is a way to represent a range of values where one expression is not equal to another. Inequalities are used to show the relationship between values that are not strictly equal. There are several types of inequality symbols, each representing a different relationship:

1. **Less than (`<`)**: This indicates that the value on the left is smaller than the value on the right.
   - Example: \( x < 5 \) means \( x \) is any value less than 5.
   
2. **Greater than (`>`)**: This indicates that the value on the left is larger than the value on the right.
   - Example: \( x > 3 \) means \( x \) is any value greater than 3.

3. **Less than or equal to (`\leq`)**: This means the value on the left is either less than or equal to the value on the right.
   - Example: \( x \leq 7 \) means \( x \) can be any value less than or equal to 7.
   
4. **Greater than or equal to (`\geq`)**: This means the value on the left is either greater than or equal to the value on the right.
   - Example: \( x \geq -2 \) means \( x \) can be any value greater than or equal to \(-2\).

5. **Not equal to (`\neq`)**: This means the value on the left is not equal to the value on the right.
   - Example: \( x \neq 4 \) means \( x \) can be any value except 4.

Inequalities can also describe ranges of values:
- \( 3 < x \leq 8 \) means \( x \) is between 3 and 8, but can include 8 while excluding 3.
