What We Love to Hear About
- Calculation errors: If a number is incorrectly classified as prime or composite, or if a factorization is wrong, please report it with the specific input. Mathematical correctness is our top priority.
- New calculator requests: Number theory is a rich field. If there's a calculation you need — Euler's totient function, modular inverse, Möbius function, perfect number checker — let us know.
- Performance issues: If a calculation is taking too long or causing your browser to freeze, please describe the input size and your device. We can optimize for common use cases.
- Educational feedback: We include brief explanations with each result. If an explanation is unclear or incorrect, we want to improve it.
- General feedback: Usability, design, or content suggestions — we read everything.
