Solutions for All Common Inequalities

The tool works with linear forms, quadratic inequalities, rational inequalities, absolute value cases, and compound forms. Each type follows known algebra rules used in school mathematics. As a result, the inequality calculator covers tasks ranging from basic homework to exam practice, without gaps or skipped inequality symbols across separate inequalities.

ai

Clear Step-by-Step Explanations

Every answer shows the solution process from start to end. A symbol changes only when a rule demands it. Each move stays visible. That way, you can see how values change on the left side, where solution sets appear, and why a value stays valid.

ai

Flexible Input Options

You can type math with symbols and brackets. Also, the system reads text from files, photos, or voice input. Hence, notes from paper or class slides fit the same workflow without format issues.

ai

Unlimited and Free to Use

You can run as many calculations as needed. Access stays open without cost. At the same time, a Pro plan adds deeper AI output and downloads.

How to Use the Inequality Calculator

The steps follow the same logic taught in class. Once the input is clear, the rest falls into place without extra effort.

image
Step 1: Enter the Inequality
Write the full mathematical statement and use symbols like >, <, ≥, or ≤. Add brackets where they belong. Stick to one variable name. Clear input helps the inequality calculator read the rule the right way.

Step 2: Run the Calculation
Next, submit the inequality and let the system handle the math. It checks where the expression equals zero on one side, adjusts signs when needed, and sorts valid ranges from incorrect answers.

Step 3: Review the Result
The output shows solution sets or intervals. Often, a number line marks the valid areas. Check the endpoints, open or closed marks, and gaps to see exactly where the inequality holds.

FAQs

What types of inequalities does this calculator support?

It supports linear, compound, absolute value, quadratic, rational, and polynomial forms based on standard algebra rules.

Does the calculator show steps or only final answers?

Calculator provides step by step solutions. Each line shows how values change and where boundary values appear. That view helps you follow the logic behind the final range.

Can I use this inequality calculator for homework or exam practice?

Yes. It helps check answers, review rules, and avoid sign mistakes after dividing by a negative during practice in solving inequalities.

How is this different from solving inequalities by hand?

Manual work builds skill and develops critical thinking. A calculator saves time and helps confirm the final answer. Together, both methods support speed, accuracy, and clear comprehension.

Is the inequality calculator free to use?

Free access covers unlimited use. A Pro tier adds extended AI responses and export options.
