Visit full site Hello there! Welcome to MathMash. We're currently working on an update for the site, so unfortunately there won't be new contests for the next few weeks. But to cover for it, we have arranged these new Daily Challenges for you. We'll update this page with a new problem everyday of varying difficulties and topics. Furthermore, solving these problems will gain you reward points, which you can exchange in our upcoming new site to get real presents! You can also receive reward points by gaining upvotes in your comments in these problems. Have fun solving the challenges!
