I am working on a take home exam that involves a system of 29 equations and 29 unknows, which I thought would be easily solvable with the TI-89. The problem is that after I pressed rref(m), and the calculator solved the matrix, I can't scroll through it. I can only get the answer for the first three equations. How can I scroll? I tried everything that I know.

I tried uploading the file on my computer, Sad
I tried copying and saving the solution Sad (computer can't read the file)

Can someone help me, I only have a couple of hours left before this is due?

I know this won't help for this exam, but if you move the cursor up to the answer (up key), you can scroll and if you press second left or second right, you can go all the way to the end.

Using [<-] and [->] you can scroll horizontally. If you want to scroll vertically, use [UPPERCASE] + [UP] or [UPPERCASE] + [DOWN] ([UPPERCASE] refers to the button next to [2nd]).
