Solving Inequalities by Multiplication and Division

In mathematics, the quantities which are not equal are represented by inequalities using symbols such as >, <, ? and ?. We have certain rules for solving the inequalities. By studying all the rules, we can do our problems easily. Every symbol has a meaning and obeys the rules of inequalities.

 

Multiplication rule

 

The Multiplication rules for solving inequalities is stated as follows:

 

If a > b, then we can multiply a positive term on this equality as a * c > b * c.

 

If a > b, then we can multiply a negative term on this equality as a * -c < b * -c.
