Notes
These resources do not aim to provide a complete list of examples of the math skills required to do well in the intermediate economics classes. All sections in this chapter may not be relevant for a specific course. These resources cover some basic mathematical tools used in economics with some examples and practice questions. There is a list of books at the end. These books discuss these topics in more details.
