Hello Product Hunt! 👋 I’m Cathy, the creator of MentalMath.cc. I built this tool because I noticed that while there are many complex math apps out there, most children (and even adults!) lack a simple, distraction-free way to build their core "number sense." MentalMath.cc is designed to be a "Daily 10-minute gym" for your brain. No sign-ups, no ads, just pure focused practice. We’ve tailored the levels from Class 1 to Class 5 to help kids transition from counting on fingers to confident mental calculation. What’s inside: Timed drills for all 4 operations. Adaptive difficulty levels. SEO-backed math tips for parents and teachers. We are currently working on an AI-powered worksheet generator for offline practice! I’d love to hear your feedback—what features should we build next? Happy practicing! 🧠✨
