Brain Game: Math Square #96


Please pay attention while traveling today, and keep an eye out for all those excited kids (and adults) who will be out and about for the Halloween holiday. To make sure you're alert, here's a new Monday Math Square at Brain Game. Good luck!

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.

Here is the SOLUTION.

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).
