              All the letters could be equal to zero! :) But I'm guessing that's not what you are looking for? Ali

                    I was sorta wondering how you would solve it by hand... I started building a rather ugly matrix for solving the vertical additions.

                          I believe there are prescribed methodologies for solving this sort of problem. But I have never used them, it might sound rude, but after a while of doing this sort of problem they become quite easy, and you learn the patterns to look for. Sometimes I use a grid system and a set of pseudo-algebraic expressions. Regardz Colin J Davies

                            I was told once by my high school maths teacher that she considered providing the source code to a program that solves a problem to be equally valid as showing the working if you did it by hand. Afterall, for problems in the "real" world, it just that you've got an answer, and can show how you got it that matters. -- Help me! I'm turning into a grapefruit!

                              I think your Math teacher is right that showing the solution is appropriate, because it show s the students grasp of the topic, But in the real world the answer is important. This particular problem would take me many pages to document clearly using true math, so I'm not going to bother attempting it. But if you are interested, in still trying it I suggest you approach the first column on the right first and discover the possible values for 'N' and 'E' then move to the second column and discover if you can eliminate the values for them.
