Readers requested a more difficult Math Square challenge, so we reduced the "free" numbers in this puzzle from two to only one. Let's see if this one fits the bill for today's Brain Game! The nine squares inside the main red grid should be filled with the digits 1 through 9. Each digit should appear only once in the mail grid. One of these numbers (the 5) is already provided for you. Place the other digits in the correct spots so that the mathematical equations work both across and down. (Remember your... READ ON

We offered our first Math Square last week, and the positive response led us to bring it back again for today's Brain Game. Enjoy! The nine squares that make up the main grid should be filled with the digits 1 through 9. Each digit should appear only once in the mail grid. Two numbers (5 and 7) are already provided for you. Place the other digits in the correct spots so that the mathematical equations work both across and down. (Remember your algebraic rules when solving the problems... multiplication and... READ ON
