(Theses days) it's hard to know what you mean by this and whether you're being sarcastic. No you don't give arithmetic students calculators for their exams, and you expect them to know how to do it without one. Yes you probably give professionals who need to do arithmetic calculators so they can do it faster and with less errors. Giving calculators to people who don't know how, why and/or when to use them will still get you bad results. Giving calculators to someone who doesn't have any use for one is at best a waste of money and at worst a huge waste of time if the recipient becomes addicted to calculator games.
