A one day workshop was conducted by the Department of Mathematics and Statistics on system of linear equations and some matrix problems in linear algebra as a part of Prof. N Dharmambal memorial Lecture series 2022-2023. The workshop was about the system of linear equations and how to solve the system of linear equations. The workshop helps to solve the system of linear equations easily. We have done more than 100 questions during the workshop. We have discussed about problems of linear algebra that are frequently asked in various competitive exams. The class was interesting to the students.
