numoku vs A

numoku is a fast-paced math game where you race to discover as many equations as possible in two minutes. Earn bonus points and awards for length, complexity, and creativity! Play against friends, other users, or practice by yourself, or, best of all, play against a robot at just your level, any time day or night. numoku is fun for ages 4 to 99. It’s especially helpful for mathematics students, teaching fluency in arithmetic and also subtly teaching foundational algebraic principles in the construction of equations.
