Title: Comparing whole numbers exercise

For Trello card: https://trello.com/c/nba88fBz/142-comparing-whole-numbers
I think the hints could be improved. I wanted to use blocks as in Representing Numbers, but there would be too many for the three-digit numbers, but I expect the hardest part of the exercise is remember what > and < mean.
