Here's a brand new *Monday Math Square *challenge for today's **mentalfloss.com** Brain Game. Good luck!

Place the digits 1 through 9 in the white blanks so that the mathematical equations work both across and down. Each digit 1 through 9 should appear *only once* in the main grid (the red square).

**NOTE: **These puzzles rarely (but occasionally) have alternate solutions that fit the rules. If you find one of these, **first make sure that you've followed the instructions to the letter, **then pat yourself on the back (and feel free to share your numbers with us in the comments).
