Section 4.3    The Multiplication  Property of Inequalities 

Multiplying (or dividing) each side of an inequality by the same positive number produces an equivalent inequality.  Multiplying (or dividing) each side of an inequality by the same negative number and reversing the order of the inequality produces an equivalent inequality.

The Multiplication Property of  Inequalities
For all rational numbers a, b, and c,
where c is positive             where c is negative
if a < b, then ac < bc  if a < b, then ac > bc
if a > b, then ac > bc  if a > b, then ac < bc 

Similar statements hold for ³ and £.

Take class notes.

Before starting your homework, rework the examples that are illustrated in this section of your textbook and the examples that I demonstrated in class. 

Then do your homework.

Write down questions (examples or concept that you do not understand).......then.............. Ask these questions in class.
