<> Program function and operation

The design of the program is a digital puzzle game , The purpose is to cultivate the mathematical thinking of children players , Improve players' mathematical ability . There are four different games in the game , They are four operations of one digit , Two digit four arithmetic , Find the best value game , Sorting game . The program can generate random questions , And can check whether the player's answer is correct . For children to feel the fun of the game , A scoring system was specially set up , There are different bonus points for answering different questions correctly , And it will be divided into different groups according to the total score 「 Rank 」, Present to player . in addition , The program also uses a more dynamic design , Let players fall in love with the game .
