Inequality

/in-ih-KWOL-ih-tee/

Definition

An inequality is a mathematical statement comparing two expressions using inequality symbols: < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), or ≠ (not equal to).

💡Example

x > 5 means x is greater than 5 (x could be 6, 7, 100, etc.). 2x + 1 ≤ 9 can be solved: 2x ≤ 8, so x ≤ 4. Unlike equations, inequalities often have infinite solutions.

Build the assessment, not just the questions

MathQuizily helps teachers move from a topic or standard to a printable math test with answer keys, balanced difficulty, and classroom-ready PDF output.

A useful assessment should make the learning target clear, cover the intended skills, and give the teacher enough information to review the result before students see it. The workflow supports short quizzes, chapter checks, diagnostic tests, homework packets, make-up assessments, and equivalent retake versions.

Choose a grade, topic, curriculum context, and difficulty level. The generated PDF includes a student version and a separate worked answer key, so teachers can print, review, and grade without reformatting questions or building solutions from scratch. No student account is required to create or print a test.
