The aim of this study is a web-resource designed to perform mathematical operations on fuzzy numbers and intervals submitted by in different formats, and provide students with theoretical information about these operations online. The objectives of the study are: analysis of different forms of representation of fuzzy numbers and intervals; development of web-resource to perform of unary and binary mathematical operations with fuzzy numbers and intervals. The object of the research is the process of teaching students computer specialties of fuzzy sets and fuzzy logic and them by practical application. The subject of research is the web-resource to perform mathematical operations on fuzzy numbers and intervals submitted by in different formats. The results of the study will be used in teaching students of computer specializations of technical universities.
