### The Full Crossnumber Puzzle!

For the Upward Bound math class I'm teaching this summer, I've been trying to get the students to create their own crossnumber puzzles. Crossnumber puzzles are like crossword puzzles, but the answers are all numbers, and the clues can contain some math. Nobody took up my challenge, so I decided to create some myself. My first attempt produced a pretty sparse puzzle, but a good first try. Below is the full puzzle, which was extremely hard to find clues for!!

Let me know what you think of this puzzle, and thanks for giving it a go!!
