Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥. \(7 \textgreater x\) reads as '7 is greater ...

For example, this graph shows the inequality \(x \textless -1\). This can be seen as there is a dashed line at -1, and the region where the \(x\) coordinates are less than -1 is shaded.
