mock-up of a basic calculator
|
(Example)
|
|
|
This mock-up of a basic calculator is realistic in that it has almost every function one can expect on a typical basic calculator. The layout will of course be different on an actual calculator. A calculator shaped like, say, a credit card will have more columns of buttons than rows.

A basic calculator can be counted on to have buttons for the basic arithmetic operations (addition, subtraction, multiplication and division). A button for square root is sometimes provided, its operation usually being ``postfix''. The percentage key, when provided, does not always behave in a standard way. For example, on some calculators, a 15% tip on a meal costing $\$ .54$ might be computed as $ 4] [2] [.] [5] [4] [+] [1] [5] [%] [=]$. \end{document} $
