Variable Inequalities

Inequalities tell you something about a variable: what that variable is greater than or less than.

Compound inequalities tell you two things about a variable: two numbers that the variable is greater than or less than.

Sometimes a compound in equality will tell you what two numbers a variable lies between.  Other times, a compound in equality will give you two distinct areas of the number line that a variable could inhabit.

Inequalities are like equations.  You solve them the same way you solve equations.  However, at the end, you do not find the exact value of a variable.  Instead you learn the parameters of a value, what it's greater than or less than.

The type of equality you're solving is deteremined by the operating symbol that replaces the equal sign.  There are four inequality symbols.
