Mathematics department, one of the founder departments of the College was established in 1939 for Intermediate students under the guidance of Sm.Snigdhaprova Mitra. Later with the introduction of undergraduate courses in the College, Mathematics was offered to the students at Pass course level.

The department then started teaching Honours Course from 1960 under the able guidance of Sm. Protibha Deb. Since then most of the students studying Mathematics Honours have completed this course with flying colours, some meritorious ones securing University rank, even one student of this department got highest marks among all students completing Bachelor course in all streams of science, arts and commerce of University of Calcutta in a recent year.

Finally the department started teaching its Post Graduate Course from 2006 with academic autonomy under University of Calcutta, with constant encouragement and support from then Principal Dr. Sanghamitra Mukherjee, previously a faculty of this department. The syllabus of this course was specially designed and a very modern field of study 'Soft Computing' was introduced as a special paper. Well known and reputed teachers have delivered lectures and taught for the PG course.

So it may be concluded that since its inception, the department has never looked back- but progressed steadily to be what it is today!
