Key concepts
3 concepts
- 1
When solving inequalities, if you multiply or divide by a negative number, you must reverse the inequality symbol.
- 2
The solution to an inequality can be expressed as an inequality, a graph on a number line, and using interval notation.
- 3
When using interval notation, we use a square bracket if the value is included in the interval and a rounded parenthesis if the value is not included in the interval.
