Final project for the Foundations course, an introductory course into HTML, CSS, and JavaScript.

Objective: To create a webpage based calculator that can process 2 number inputs with an operator input (i.e. 2 + 2) and display the answer.

Goals:

1. Must be able to process addition, subtraction, multiplication, and division.
2. Cannot use the eval() function built into JavaScript.
3. Have a clear button that will wipe out any existing data.
4. Display an error message when trying to divide by 0.

"Extra Credit"

1. Add a decimal input to allow for entry of floating point numbers.
2. Add a backspace button to delete the latest entry in case of an error in input.
3. Add keyboard support.
