In this session, we will explore several different bases/number systems that are used in computers and other parts of computer science! Some bases that we will cover include, but are not limited to: - Binary (Base 2) - Octal (Base 8) - Hexadecimal (Base 16) We will learn how to convert a number from decimal (base 10, what we usually use in our everyday lives) to any different base, convert from a number in a different base to decimal, and convert a number from a different base to another (non-decimal) base! Pre-requisites: There are no pre-requisites, except for knowledge of the basic operations (multiplication, addition, etc.), and the desire to learn new things!

In just one hour, get ready to learn all about recursive functions, also known as piecewise functions! By the end of the session, you will have all the fundamental knowledge necessary to solve recursion-related problems! Pre-requisite: Please be comfortable with equations, variables, and the basics of functions. It is totally alright if you are not very familiar with functions, feel free to ask any additional questions during class. Additionally, you can check out the functions chapter from Khan Academy's Algebra 1 course.

We will be going over three main data structures that are essential in many algorithms: - Stacks (Recursion-based) - Queues (Useful in BFS) - Binary Search Trees (Fast search algorithms) This session does not involve any programming, so no programming experience is required, and we will be learning these algorithms from scratch, so don't worry if you haven't heard of these data structures before!

Learn the fundamental concepts in computer engineering, from computer number systems to digital electronics! We will cover topics like prefix/postfix/infix notation, boolean algebra (a combination of logic and algebra), and the basics of graph traversals and adjacency matrices. This course will follow American Computer Science League (ACSL) materials, and will help prepare you for the contests. It will equip you with the necessary knowledge to start your computer engineering journey, even if you don't plan on taking the contests! Please note that this course is meant to teach you the core concepts in computer engineering, which will be helpful for both engineering and computer science. These topics are useful in programming, but as we will not be covering programming tasks, no programming experience is required.
