About

Over the next four weeks, we will meet semi-weekly—on Mondays and Fridays—to go over everything you need to know about complex numbers to achieve a 100% score on the Khan Academy Unit test. We will cover the imaginary unit, "iii﻿
"; the complex plane; adding, subtracting, and multiplying complex numbers; and quadratic equations with complex solutions. We will also have additional sessions some Tuesdays and Thursdays to review what we have previously learned in the series.
Sessions are relatively slow-paced and might go overtime.
