Numbers and arithmetic Lecture 1 Review of Algebra

This is the first video in my short refresher course on algebra. The course consists of 10 lectures and the notes together with instructions are available at blogs.gwu.edu/juanklopper/edu...
Each lecture has a note (see link above) and two video lectures. The first takes a traditional pencil and paper approach and the second shows you how easy it is to use Python to do your mathematics. You do not need to know Python or even install any software. As long as you have a Google account.
Watch • Setting up Python for ... to see how to set up your Google account for writing Python code. It is just like using Google Docs.
The course is a quick review of the algebra you learned at school. It is just the essentials that you need before taking courses in data science.
