Brain Game: Math Square #74


The Brain Game kicks off another week here at Today's Monday Math Square is a bit unusual, in that five of the six calculations result in the number 2. Will this make the challenge easier or more difficult? Find out below. 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 my 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 it with us in the comments).
