What are they?
A calculator is a device for performing numerical calculations. It should not be confused with a calculating machine. Nowadays many people have a calculator with them as part of their mobile phone and/or personal digital assistant. Engineers and accountants make use of calculators for problems where a computation is not complex enough to demand the use of a general-purpose computer. In most developed countries, Students use calculators for schoolwork.
