Math Stan vs Zero to a Hundred

What if the world's top genius was living among us, but no one even knew? Could it be one of your friends? Could it be you? Let's find out once and for all in a worldwide competition of Math Stan! When the timer starts, you get 30 seconds to answer as many questions as possible. Key in the correct answer, and you gain a valuable point and extra time. But be careful, my friend. If the incorrect answer is tapped, you will receive the dreaded ONE POINT DEDUCTION! Can you handle this pressure? Some say the timer is too fast. Others say the competition is too intense. Most say the frantic music isn't really conducive to mathematical concentration. MATH STAN!

Grind daily to build your advantage. • Claim your spot on the Worldwide Leaderboard, ranked by Highest Scores and Longest Streaks! PRACTICE MODE • No clock. No penalties.
