What you need to know:
Whilst an equation is a mathematical statement that includes an equals sign, an inequality is a mathematical statement that includes any one of <, \leq, >, or \geq.
Inequalities express a range of values, for example 3 < x \leq 6 tells us that x may be any number that is bigger than 3 but smaller than or equal to 6. You may be asked to firstly solve an inequality (which is very much like solving an equation, with one or two extra caveats), and secondly to be able to display your answer on a number line. For example, the inequality 2x - 5 > 3 can be rearranged to show that x > 4. Expressed on a number line, this looks like:
It’s important to remember that the open circle is used when the equality is strict (<, or >) and the filled-in circle is used when it is inclusive (\leq or \geq).
