Calculators are devices that perform numerical operations, typically including the basic operations of addition, multiplication, subtraction and division, but possibly going further to include evaluation of more advanced functions and even the ability to draw graphs. Calculators are distinguished from computers by the fact that their abilities are limited to a certain set of operations. But this line is becoming blurred as more advanced scientific calculators can perform computer algebra and can execute programs written in with own programming language.
