# Department of Mathematics

The Mathematics Department is located in the Kamayut Campuses and Ywathagyi Campuses of Yangon University of Economics. Professor Dr. MyintWai is the Head of Department.

His research is in Combinatorial Mathematics. Currently, the department of Mathematics being run with total teaching staff of fourteen: one professor (Head of Department), six lecturers, four assistant lecturers and three part-time tutors.

For the time being, the department of Mathematics, as a supporting department, offers the course on Business Mathematics, Applied Mathematics and Pure Mathematics to students who are specializing in respective academic disciplines like “commerce, accounting, business administration, statistics, population studies, economics, public administration and development studies”.
