You'll put your debugging skills into practice along with some of the other programming skills you've acquired for this project. You will build out a calculator with some basic functions: add, subtract, multiply, and divide. As with previous assignments, when you look through the code that's provided, you'll find any lines marked with TO DO as a call for you to do something.

1. To start, fork this repository.
2. Clone your forked repository to your computer.
3. Modify the files and, when you're ready to submit, commit changes to complete your solution.
4. Push/sync the changes up to GitHub.
5. Create a pull request on the original repository to turn in the assignment.

• .travis.yml: do not edit this file, it is used for automated testing
• calculator-runner.py: this file sets up the program and runs the functions in calculator.py. You don't need to edit this file but you can take a peek, if you'd like. If you do edit, edit at your own risk!
• calculator.py: you'll need to edit this file, it contains some empty functions, and some comments that start with TODO that will detail what you need to do for full credit.
• test_ticTacToe.py: do not edit this file, it is used for automated testing
