Economics uses many subfields of mathematics to model human behavior. Here, we provide an introduction to Calculus and Probability Theory
Calculus provides a framework for modeling systems in which there is change, and a way to deduce the predictions of such models. Human behavior is a system subject to changes.
A "sequence" is an ordered list of numbers called "elements" or "terms" of the sequence. A "series" is what you get when you add up all the terms of a sequence. For instance, "1, 2, 3, 4" is a sequence, with terms "1", "2", "3", and "4"; the corresponding series is the sum "1 + 2 + 3 + 4", and the value of the series is 10. Sequences and series are extremely useful is real life. Here are some examples of them, their history and some applications.
Economic events can rarely be predicted with certainty. Modeling economic choices and outcomes often requires to resort to probability theory.
