Yes of course. These are calculators - they are meant to reliably calculate things.
I think the difference is that building 60 interactive calculators manually would force you to do a lot of manual testing. If someone built up that many interactive calculators I would imagine a lot of attention has gone on each one. Why would they spend so much time on something and not test it?
