Computers don't think, they calculate. Use computers for calculations. To understand mathematics, don't use a computer; use a text book. If you don't understand mathematics, then you can't be thinking but only guessing. That's what I've seen students do, to use a calculator as a guessing machine, checking their guesses until they get an answer they guess is correct.
