MathsSoc is the official Students’ Mathematics Society of the University of Jaffna.

MathsSoc is the official Students’ Mathematics Society of the University of Jaffna. Previously the society ran many events including talks and a regular quiz. A challenging problem would be given to students with a competition for the submission of correct answers. Currently the society is not active, due to the situation and lack of staff. If any Science Faculty students are interested in starting up the society again, please see a member of the department staff. A small annual budget has been allocated by the University to the society, to run events etc. To function properly the society would require a number of officers, including a President, Treasurer and Secretary.

On this page you will find some simple maths puzzles, and perhaps more importantly a list of useful maths websites. These include links to “international mathematics societies and organisations and information for maths careers and further studies, including English language tests.
