Coding theory

Coding theory is a branch of mathematics that is used to create codes. A code is a way to send information in a way that can be read and understood, like a secret code or a computer program. In coding theory, mathematicians use equations and other tools to come up with systems that can be used to create these codes. The codes are like puzzles that you have to figure out before the information can be read successfully. Coding theory is like a game of secret messages, where the person trying to decode it must figure out the code!
