Inequalities

What are Inequalities

Inequalities represent relations between numbers that are not equal to each other. These are the main symbols that represent inequalities: not equal to less than greater than less than or equal to greater than or equal to These symbols allow us to show the relationships between numbers. For example, we can say that 3<x<5. However, there is a lot more that we can do with inequalities.

Representing Inequalities on a Number Line

To represent inequalities, we can draw number lines and plot the different inequalities on these number lines. This allows us to display the value of the inequalities with unknowns in relation to other inequalities. It also enables us to see the exact range in which the unknown can be found on the number line

Representing Inequalities as Regions

We can also represent inequalities graphically. By drawing graphs and solving the inequalities, we can sketch and create regions which allow us to show the exact value that an unknown could have in an inequality.
