What is the Inequalities Calculator?

The Inequalities Calculator is an interactive online tool designed to solve linear inequalities of the form:

ax + b < c, ax + b > c, ax + b <= c, ax + b >= c, ax + b == c

Where:

a is the coefficient of x
b is a constant term
c is the value on the other side of the inequality
<, >, <=, >=, == are the relational operators

Instead of manually solving each inequality step-by-step, this calculator automatically evaluates the solution for you. It is ideal for students, educators, and anyone who frequently works with mathematical inequalities.

Tips for Effective Use

Always double-check the input expression format: ax + b < c.
Avoid non-linear expressions such as x^2 + 3 < 7 as this calculator focuses on linear inequalities.
Use parentheses carefully if your constants or coefficients are negative.
Combine with other math tools for a complete problem-solving approach.

Common Mistakes to Avoid

Entering equations without the variable x.
Using unsupported operators like != or ≈.
Inputting non-linear or quadratic inequalities.
Forgetting to include a constant term (if required).
Adding spaces in irregular patterns that may confuse the parser.
