MathMind - Arithmetic memory challenge

I built MathMind as a simple yet powerful tool to help users boost their arithmetic speed and memory. Inspired by international competitions where participants solve a sequence of numbers and operations shown one by one, MathMind brings that challenge online. It’s not just about getting the right answer, but also about improving mental calculation and recall. If you want to sharpen your mind and calculation skills with a focused, no-frills approach, MathMind is for you!
