Objective of the research: research on the process of solving mathematical problems and ability level in solving mathematical problems. Research methods: theoretical research, the author relies on relevant domestic and foreign research documents to analyze and give personal opinions; Practical research: deliver learning cards with practical and math problems to 9th grade students. Research results: The author proposes 6 steps for solving mathematical problems, then the author studies, tests and gives 8 specific stages in the process of solving mathematical problems of students. At each stage the author shows its characteristic manifestations. This research is the initial basis for ability to detect and solve problems for students in teaching Maths at Secondary schools. | Research on solving mathematics problems of secondary school students
