In this course, students can apply basic mathematics to make and break secret codes. They learn about encryption systems ranging from the basic Caesar cipher to the modern day RSA algorithm. Mathematical concepts such as positive and negative  numbers, decimals and percents, data analysis and probability, prime numbers and factorization, modular arithmetic, inverses, and exponentiation are applied to encrypt and analyze codes. Students also explore historical events and the impact cryptography has left on them.

Course Length: Typically 3 months
