Crossword Puzzle

Welcome to day 2! Today I felt like setting a crossword puzzle, but then I though maybe that's not coding related enough. So I thought about making one of those Math puzzles we all did in school. Those both sounded fun and I couldn't decide between strings and numbers, but then I realized, if you can add subtract and multiply both, why not mix them? Today's task is to fill out the puzzle bellow. Allowed characters are 0-9, minus, quotes, and decimals.
