It's a math quiz app designed to improve users' math skills through fun challenges. Users can choose different levels of difficulty (such as "Easy", "beginner", "Intermediate", or "hard") according to their level, and solve as many problems as possible in the limited time. The app offers four levels of difficulty, from basic arithmetic to complex calculations, for players of all levels. Difficulty determines the numerical range and complexity of the problem. Each question has a limited time (30 seconds by default), and the answer will be automatically moved to the next question after the countdown. There is a record of answers.
