    Several inequalities can be combined together to form what are called compound inequalities.<\/p>\n

    The first type of compound inequality is the \u201cor\u201d inequality, which is true when either inequality results in a true statement. When graphing this type of inequality, one useful trick is to graph each individual inequality above the number line before moving them both down together onto the actual number line.<\/p>\n
