Unit 3: Variables and Math in Processing
This unit will walk your through Chapter 4 of Getting Started with Processing. It begins to lay the groundwork for much of the course. Please do not hesitate to read further in the Processing reference or ask questions.
 Introduction to Variables and Data types  Read, watch, and take notes. Variables will be used throughout the course and are very important in all programming.
 A Little Math  Read, watch, and take notes. Pretty much any of the math you've been learning in your math classes can be used in Processing. It can actually be really useful.
 Repetition  Read, watch, and take notes. Computers are really good at doing the same thing over and over again. In this lesson you'll harness both the power of variables, but even the power of math with variables.
