About This Calculator

Why MathAI GPT is different from traditional calculators

Half-life is the time for a quantity to reduce by half. It's used in radioactive decay, pharmacology, and any process with constant proportional decay.

Common Uses

  • Calculate amount remaining after N half-lives
  • Find half-life from decay constant
  • Convert between half-life and decay rate
  • Model real-world decay scenarios

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
