brief introduction

In mathematics teaching, practical problems including some mathematical relations (such as quantitative relations and geometric figure position relations) are described by language or words, and the problems formed in this way are called application problems. Any application problem contains two parts. The first part is known conditions (conditions for short), and the second part is seeking problems (problems for short). The conditions and problems of application questions constitute the structure of application questions.
