Crazy what they have these days. Back when I was in high school (first year they required the 83) our teachers simply required we showed every step. So we could get the answer with a few key presses, but unless we showed how to get the answer we wouldn't get credit. Of course I wrote programs to solve the problems step by step and print out the answer, but I guess the system works because in the process of being clever and writing the programs I of course learned how to solve the problems step by step.
I had a nice and crazy little Chinese professor for numbers theory in college. I never knew what he was saying, but he would tell us the questions for the exam the day before. I asked him if I could use my ti-92+ and he said yes, so I just programmed in brute force algorithms, entered in the data, then sat back while the 10MHz processor crunched.
