Calculators putting aside their differences and coming together
Adding machines and calculators both perform basic mathematical calculations, but their two machines differ in their operation, features, and functionality.
The biggest difference between adding machines and calculators is that adding machines provide a printed receipt for each entry and calculators display information on a screen.
Adding machines accept numeric entries followed by mathematical function indicators.
Calculators accept the mathematical function followed by the number.
Because adding machines feature the additional functionality of printing each entry, the adding machines often feature special keys to control the paper advance or display subtotal information.
Adding machines perform basic mathematical functions (addition, subtraction and multiplication)
Calculators can perform advanced functions (calculus and trigonometry).
Calculators are used in schools, universities and numerous professional applications.
Adding machines typically are used in banks and accounting firms.
