Numbers and Arithmetic

Numbers are everywhere around us: small numbers, large numbers, fractional numbers, negative numbers, percentages, ratios, and many more. These chapters will help you understand different kinds of numbers, what you can do with them, and what interesting properties they have.

Geometry and Shapes

Geometry is one of the oldest areas of mathematics: the laws of angles, triangles and circles were discovered by Greek scientists more than 2500 years ago. Geometry is also one of the most fun and beautiful parts of mathematics, and it has applications everywhere from architecture to astronomy, engineering or computer games.

Functions and Equations

Mathematics is not just about numbers or shapes - it is about abstract concepts and relationships. Algebra is the language which allows us to describe and understand these ideas. It is the foundation for all mathematics you will learn in the future, and has infinite applications.

Discrete Mathematics and Probability

Every day we use the topics from this section in some way - often unconsciously. Data lets us analyse and understand the world around us. Probability helps us make decisions. Codes let us to communicate with each other. And Graphs make up all transportation networks.

Core Mathematics

Building up on what you’ve already learned, these chapters will expand and formalise the core tools and concepts of mathematics: logic and proof, algebra and functions, sequences and series, complex numbers and polynomials.

Pure Mathematics

While the purpose of most sciences is to solve real world problems, pure mathematics is studied for its own sake. We want to investigate abstract patterns, structures and principles, and prove new results using a consistent logical framework. But of course, even pure mathematics has many real applications.
