Film Series One: Mathematical Review

In this series of films we review some basic ideas in mathematics. You may be familiar with these ideas but you need to be sure about them, as they are fundamental building blocks for what it to follow in a course of mathematics for economics. This programme will review the foundations to develop understanding of more advanced concepts. For example, how do people make choices when they are unsure about the outcome of their decisions? How do governments make decisions about which road building schemes are worthwhile?

These video clips and animations can be viewed in isolation, or you can use our learning pathway and follow links to related material in MathsEG.
