Example Program: VariablesAndSimpleMath.bs2
This program demonstrates how to declare, initialize, and perform operations on
variables.
' Robotics with the Boe-Bot - VariablesAndSimpleMath.bs2
' Declare variables and use them to solve a few arithmetic problems.

Default Value - If you do not initialize a variable, the program will automatically start by
storing the number zero in that variable. That’s called the variable's default value.
