 * Description: These are the basic required components of a simple Java program
 *  This program initializes five variables with descriptive names (that have 
 *    incorrect values), prints their name and their value in the terminal, 
 *      changes the value of the variables to the correct values using 
 *   mathematical operations, and prints out the new values in the terminal
 *
