Alright, so, as a hint, one way to test a number to see whether it is even is to use the modulus operator `%`. You can test whether something `% 2 ===0`. Just guessing on the hints here. Let me know if you have any particular sticking points with this part of the homework. Everything else in your work is great. I'll merge your pull request when you finish this, unless of course you want to take some time to tackle the Roman Numerals assignment.
