Welcome to the Monday Math Square, designed to get your noggin in gear to start the week. Enjoy!
NOTE: I made an error in an earlier version of this math square (completely my fault) but it has since been corrected. Apologies to anyone who spent time trying to solve an unsolvable puzzle. I'll remain in the corner until I've learned my lesson.
The nine white squares inside the main red grid should be filled with the digits 1 through 9. Each digit should appear only once in this main grid (the red square). Place the digits 1 through 9 in their correct spots so that the mathematical equations work both across and down.
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 it with us in the comments).
