Interval Notation
This algebra video tutorial provides a basic introduction into interval notation. It explains how to express the solution of an inequality using a number line and interval notation. Examples include compound inequalities. You should use the parentheses symbol next to an infinity symbol or for open circles on the number line. You should use brackets whenever you can encounter a closed circle on a number. This video contains plenty of examples and practice problems on interval notation.
