Inequalities: Multiplication and Division Techniques

  • If both sides of an inequality are multiplied or divided by the same positive number, the resulting inequality has the same solutions as the original one.

  • If both sides of an inequality are multiplied or divided by the same negative number, the direction of the resulting inequality must be reversed. The new inequality has the same solutions as the original one.
