The paper focuses on the parallels, which are rooted in the simultaneous development of mathematics and informatics. Both mathematics and informatics are based on problem-solving. However, the approaches to determining problems, solution techniques and interpretation of results are different. The paper shows different approaches of mathematics and informatics for solving a simple problem from the informatics competition. It was presented for students, who would be future informatics teachers, and it has become the beginning of the discovery of unexpected relationships and rules’ chain, the source of successive tasks, and various methods of their solution. The paper brings the results of the constructivist teaching of students in the form of a fictional interview of mathematician and informatician. Fictional cooperation of a mathematician and an informatician in analysing and solving problems will allow for a detailed analysis and comparison of both fields, which will lead to determining both common and different elements.

分析数学和信息学解决任务的不同方法和教育意义

本文着重于相似之处，这些相似之处源于数学和信息学的同步发展。数学和信息学都基于解决问题的能力。但是，确定问题的方法，解决方案的技术和结果的解释是不同的。本文展示了解决信息竞赛中一个简单问题的不同数学和信息学方法。它是为将来成为信息学教师的学生而设计的，它已成为发现意外关系和规则链，连续任务的来源以及各种解决方法的开始。本文通过对数学家和信息学家进行虚构的访谈，为学生提供了建构主义教学的成果。
