GeekDad Puzzle of the Week: Numeric Crossword Puzzle

Most everyone that reads GeekDad has at least one friend or co-worker that can recite Pi out to a few dozen digits — or, more likely, we are that friend or co-worker. A lot of us probably have quite a few numbers “embedded” in our brains, like old street addresses, telephones numbers, or locker combinations. In honor of these figures we just can’t get rid of, this week’s GeekDad Puzzle of the Week is a Numeric Crossword puzzle.

Or would it be better named a Crossnumber puzzle?

Update: Many thanks to the first few posters that (correctly) identified that a last-moment renumbering inserted a few “puzzle gremlins.” I believe that they are all addressed!
