Monday Math Square #157
Here's a brand new Monday Math Square to start off this week's quintet of mentalfloss.com Brain Games. Enjoy!
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).
