I never was hurt. I was just teasing you.

And I hate sudoku.

And you have to waste your time reading this.

But these letters are the numbers 1,2,...,9 in some order thus,

Thus,

Then in the third equation we have that which is a violation because it cannot be more then 9. - February 28th 2006, 08:33 AMtopsquarkQuote:

Further, they if they are not distinct then it solves easily for example,

A=4

B=1

C=3

D=9

E=1

F=1

G=6

H=2

I=9
