About This Calculator

Why MathAI GPT is different from traditional calculators

Inequalities work like equations, with one key difference: multiplying or dividing by a negative flips the direction. Solutions are usually ranges, not single values.

Common Uses

  • Solve one-variable linear inequalities
  • Graph solutions on a number line
  • Handle compound inequalities
  • Apply inequalities to real-world constraints

Key Advantages

Shows each logical step — not just the final answer
Understands free-form math and plain language together
Accepts images of handwritten or printed problems
Helps you learn the method, not just copy answers
