This is puzzle #1 from the 9x9 hard math crossword set. The board uses addition, subtraction, multiplication and division, starts with 1 given number, and leaves 18 cells for you to fill from the tray. Every row and column forms an equation, and there is exactly one valid solution. Work from the lines that already have two numbers, then use each crossing to narrow down the rest.
