Good job on making it to the end of Variables and Operators! In this lesson, we learned the following:

• How to create variables in a variety of ways
• Variable types and constrained variables
• Listing and creating environment variables
• Manipulate variables and data with operators
• Using arithmetic operators to perform mathematical operations
• Using assignment and unary operators to change data
• Using equality and type comparison operators to compare two pieces of data
• Using logical operators that enable us to create complex comparison statements
• Order of operations
