The book provides an overview of the mathematical skills essential for pursuing a degree in economics at a university. It can be used for both a bridging course in mathematics and an introductory lecture in economic mathematics. The focus is deliberately placed on acquiring calculation skills before using a graphing calculator and the formal treatment of the material. The mathematical relationships are explained in detail and tailored to the target audience. The authors provide comprehensive sample solutions that apply the learned concepts and practice an appropriate presentation of the solution process. The material to be learned in the field of analysis is organized by function properties rather than, as is often the case, by function classes. This allows for significantly faster learning success.
