About the Inequality Calculator

Check whether an inequality such as 5 < 8 is true, using less than, greater than, equal and not-equal operators.

How to use the Inequality Calculator

  1. Enter the Left and Right values or expressions.
  2. Choose an operator: <, >, ≤, ≥, == or ≠.
  3. Use Add Evaluation Field to check more comparisons and read each result.

Formula and method

An inequality compares two values. It is either true or false. For example 3 ≤ 3 is true, and 4 > 7 is false.

Tips

  • Multiplying or dividing both sides by a negative number reverses the inequality sign.
  • ≤ and ≥ include equality.
