My Trig teacher, which was the class where I got my cherished TI-83+, had the exact same opinion of my little TI-Basic programs which worked the same way as yours.
I got an A in that class both semesters, which was better than the B I often got in Math (and a C- once in AlgII) because I hated doing homework. But starting on the program as soon as I grasped the concept and usually blasting through the homework with it by the end of the period meant an A was easily in my grasp.
That teacher was the best damn math teacher ever. He would work hard to help every last student get it, he'd gladly spend his whole lunch helping a kid if they needed it.
PS. I did share some of my programs, mostly with one girl, but she's a successful nurse today so I guess I didn't ruin her future :D
You should send that teacher an email today! They don't hear often from their past students
