An inequality is a relationship that holds between two values that are different.

*a*<*b*means that*a*is less than*b*(or, equivalently, that*b*is greater than*a*).*a*>*b*means that*a*is greater than*b*(or, equivalently, that*b*is less than*a*).*a*≤*b*means that*a*is less than or equal to*b*(or, equivalently, that*b*is greater than or equal to*a*).*a*≥*b*means that*a*is greater than or equal to*b*(or, equivalently, that*b*is less than or equal to*a*).

## Hint:

Can you:

- Explain the meaning of each inequality symbol?
- Show how each type of inequality is represented on a number line?
