This is the hard one that I'm challenging people to figure out.

This one was done the same way as one of Magnet's last ones.



I'm lost, I spotted a few repeating patterns, but it doesn't seem to lead me anywhere.
Good eye though, Mark!

Close, I used a random character generator, I only used the first 16 letters of the alphabet to introduce a red herring. :)

Here's a simple example. Start with the word MATH. Change it to its ordered alphabetical equivalence =>13, 1, 20, 8. Write in vertical order, that is row one is 13, 20 and row 2 is 1 ,8 as a square matrix. (I've been spoiled with equation editor and can't seem to get the program on here to do matrices for me.) Then get yourself a coding matrix. I made up: row one -2, 1 and row two 7, 10. Multiply the coding matrix by your original matrix. The result is the encoded matrix of row one -25, -32 and row two 101, 220. Thus, your "coded" word is -25, 101, -32, 220. To use this method you must have square matrices so you fill in zeros if it is not square. To decode the matrix you would need the inverse of the coding matrix. Maybe this isn't for everyone, but interesting to math geeks.

I figured out how to do matricies:
\(\left| \begin{array}{ccc} \ 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{array} \right|\)
This is the line to produce it
[tex][\left| \begin{array}{ccc} \ 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{array} \right|[/tex]
There's a sticky at the top of the Math forum that explains some of it.

Thanks! I had found the symbols but I wasn't putting my numbers in quite the right place or using the &. I should have looked for instructions-- after all I am a girl and can do that!:)

Mine was actually an answer to 1chance's call for help on vbulletin tags.

What do you mean by "did you mean homework help in general?"
