* Math only:
* int: stores whole numbers
* double: stores numbers with decimal points
*
* boolean algebra
* boolean: stores a true or false value
*
* text
* char: stores a single character
* String: stores a string of characters

* How to output text to the terminal.
* String x = "And this is how you output variables with println."
* System.out.println("This is how you type stuff in manually. " + x);
*
* Variables cannot share names, each variable must have an unique name!!!

//#7. Write code that checks a number to see if it is an even number or not.
// Hint: There is an operation called modulus (%) that returns the REMAINDER of a number after dividing.
//#8. Write code that when given three grades, it returns the average of those three grades
//# AND returns a letter grade as well based on the average.
// Example: Inputs: 94, 87, 75 Outputs: 85.333, B
//#9. Write code that checks whether a boolean variable is true or false, and then outputs a special message
//# based on whether the boolean value is true or false.
// Example: myboolean = true Output: "This boolean is true" myboolean = false Output: "This boolean is false"
//#10. Challenge: Write me a program that can simulate a game of rock paper scissors, given two inputs
//# The inputs can either be "rock", "paper", or "scissors".
//# The output dictates which player won the game.
// Example: Player 1: "Rock" Player 2: "Paper" Output: "Player 2 wins!!!"
