  • Multiplying and Dividing Inequalities

    Maybe you are wondering whether there are Multiplication and Division Principles for Inequalities. The answer is yes, but they aren't quite the same as the Multiplication and Division Principles for Equations. When we multiply or divide both sides of an inequality by a* positive* number, we do get and equivalent inequality. But when we multiply or divide both sides by a negative number, we must *reverse the inequality sign *to get an equivalent inequality.
