Waaaay back at school in the 90s, that was the policy in our public exams, we were allowed the calculator but it would be wiped on the way in to the hall.
So I memorised my quadratic-solver-with-intermediate-steps and tapped it back in while we were waiting for the test to start :)
The calculation was not hard, but it was still faster just to run my program and scribble down the steps it spat out than to do the solving manually each time it came up. IIRC I had one for simultaneous equations too.
