Chapter 2 Algorithms

Algorithms are important to mathematics and other sciences. They give a structured way to explain a process in detail. Algorithms consist of instructions that can be executed by human beings or machines. Machines, usually computers, follow instructions they are given in a (limited) language called a programming language.

In this course we will not program computers but will nevertheless introduce a handful of instructions that we use to formulate our algorithms. These instructions will clarify how the algorithms should be executed.
