While in my Algebra II class, we were studying polynomial expansion, and I wrote a program on my TI-85 that would not only expand things like (2x^2 + x + 3)^4, but it would show the work. I literally just had to enter a couple values and then verbatim copy what it spit out onto the paper. I asked the teacher if I could use it on the test, and she was like "If you can write a program that doesn't just solve it, but shows the work, then obviously you know the material incredibly well, so there's no need to make the test tedious. Go for it, just don't share the program with any of your friend." The last bit was easy because I didn't have any friends. :-(
