The problem is that many students are confused about how to solve inequalities. This is especially true for high school students who are studying precalculus as a preparation for calculus in college. 

Fortunately, there are many programs that can help students understand how to solve inequalities and prepare them for more rigorous calculus classes. Ideally, these programs will explain the concepts in a way that teenagers can understand and practice with little to no error or confusion. 

How to Solve Inequalities With Interval Notation

Using interval notation is an important part of solving inequalities in precalculus. It is a method of representing the solution set to an inequality in a way that allows it to be easily recorded and manipulated. 

To solve an inequality with interval notation, the student must divide a set of real numbers into test intervals and choose a test point from each to determine the sign of the left side of the inequality. Then, the student must tabulate these intervals and write down their corresponding signs. 

Finding Inequalities Using Graphing and Trigonometry

Students who have a strong grasp of the principles of math, including graphing, will find it easier to understand how to solve inequalities in precalculus. In fact, many educators say that having a good understanding of graphing and trigonometry is one of the keys to success in calculus. 

How to Solve Inequalities with Graphing

A student who is able to solve inequalities using graphing will be able to apply these skills to a variety of math problems, from finding the value of a given function to creating and analyzing simple linear equations. In addition, graphing will give students a more visual understanding of the mathematical concepts they are learning and help them to better retain information. 

How to Solve Inequalities in Algebra

Having a strong grasp of algebra will make it much easier for students to find the derivatives and antiderivatives of functions. In addition, students will be able to use algebra to analyze and manipulate complex functions and transform them into different forms. 

How to Solve Inequalities Using Graphing

A great advantage of graphing is that it is a more flexible method of solving inequalities. It can be used to create or manipulate any number of different types of functions, such as quadratic, exponential and logarithmic. In addition, graphing can be used to identify the intervals over which a function increases or decreases and to determine how to perform transformations on a function. 

How to Solve Inequalities at the High School Level

Whether you are a teacher, counselor or student, it is essential that you have a clear understanding of how to solve inequalities at the high school level. If you can master these skills, it will greatly improve your chances of succeeding in any math course and ultimately in your career.
