Relationships symbols are used in mathematics to show how to numbers or expressions are related to each other. The most commonly used symbol is the equal sign = which is used in every equation.

= Equal

≠ Not equal

~ Approximately

< Less than

__<__ Less than or equal to

> Greater than

__>__ Greater than or equal to

A way to remember the < and > signs is that they **always**
point to the littlest number.

For those of you interested in computer programming, you need to know that the relationship symbols are used in a very different way from their mathematics definitions. This is probably one of the most difficult concepts to learn when you are beginning programming.
