The images for the Monday Math Square just wouldn't work yesterday due to upgrades on the site, so we're trying something totally new and revolutionary, a Tuesday Math Square. Wow, huh? Enjoy! The nine white squares inside the main red-outlined grid should be filled with the digits 1 through 9. Each digit should appear only once in this main grid (the red outline). Place the digits 1 through 9 in their correct spots so that the mathematical equations work both across and down. Here is my SOLUTION.... READ ON

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... READ ON
