The subject of mathematics is often paired up with other subjects such as education, statistics, finance, and computer science. This pairing can give added value in the teaching, computer programming, and financial forecasting and planning fields.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
