Learn how to solve (mathematical) inequalities. A key concept in this tutorial is flipping the inequality sign when multiplying or dividing both sides by a negative number.
Our discussion of linear inequalities begins with multiplying and dividing by negative numbers. Listen closely for the word "swap." Super important!
In addition to solving the inequality, we'll graph the solution. Remember to swap if you mutiply both sides of the inequality by a negative number.
Practice solving inequalities in one step.
Inequalities are more than abstract concepts and exercises. They help solve real life problems. Here's an example.
