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. IMPORTANT: Remember algebraic rules when solving the problems... multiplication/division should be performed in the first step, then addition/subtraction in the second. Good luck!
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, particularly when it comes to the order of operations, then give yourself a pat on the back. Nice job!
