Welcome to the study space! We'll use the Pomodoro timer to help you focus on finishing whatever you need to do. If you have any questions about topics I (Wenbo) am certified in (including pre-algebra, algebra 1, algebra 2, geometry, trigonometry, pre-calculus, statistics, college algebra, calculus, and AP Precalculus/Statistics/Computer Science A/Psychology), feel free to ask me during the session! More sessions will be scheduled over time to avoid unforeseeable schedule conflicts. By the way, this is a continuation of the previous series, [https://schoolhouse.world/series/22685](https://schoolhouse.world/series/22685).

We will review imaginary numbers, from the basics to a complex number of polar forms; no prior knowledge is required. Bring paper and a pencil and participate in class!

This course focuses on building a comprehensive understanding of radicals and rational expressions as part of Algebra 2. Through interactive sessions, students will learn to simplify, operate with, and solve equations involving radicals and rational expressions. Key skills include finding the least common denominator, rationalizing denominators, simplifying expressions, and solving radical equations. The course includes real-world applications, mixed problem-solving, and regular reviews to reinforce learning. By the end of the course, students will confidently handle radicals and rational expressions in algebraic and applied contexts.

This series is for people with no prior knowledge to learn topics like: - Imaginary numbers - powers of imaginary units - Complex number structures - Addition, subscription, multiplication (maybe division but it is considered part of precalculus) Bring paper, a pencil, and a calculator!

The series is only four days long. We will cover the foundation of Algebra 2, which is polynomial arithmetic. No prior knowledge is required. Bring paper and a pencil and attend any session you need.
