We strive to spread the beauty of mathematics. We believe that curiosity is the best teacher. That's why we select fun and interesting problems to keep you engaged. Considering the inconsistency of the math level of different people, we avoid problems that are too difficult or that require advanced knowledge. We try to explain them in an understandable way for anyone with middle school math knowledge. That said, these problems are not going to be easy. Thus, be prepared to take your time and make an effort.

When you solve a problem, see whether you can brainstorm another solution. Look at your solution, ask yourself what strategy you use and think how you can apply these ideas further.

Through our selected math problems, we hope to broaden your perspective, develop new methods, savor the thrill of critical thinking, unleash your creative potential, and push the boundaries of your mind. Laying a solid foundation in knowledge and problem solving skills will open the door to success in many subjects.
