Key Features
Many calculators are designed to be pocketed and carried around. There are, however, many boxier machines designed to be placed semi-permanently on a desk. These devices have flat bottoms and often have wider buttons. Desktops come in a standard size as well as a small size.
There are three primary types of calculators. Basic calculators are able to do basic arithmetic. Business and scientific calculators generally include many other functions necessary for statistical analysis and higher level math. Graphic calculators are those able to actually display small images, such as graphs.
Calculators that come with the print option are often referred to as adding machines. They offer the option of leaving a paper trail of all (or just some if you prefer) of the calculations you do using the device.

Other Functions
There are various ways of powering your calculator. Solar energy powered calculators have a small solar panel that generates energy when there is sunlight. There are also calculators that use batteries in conjunction with solar power, or just batteries alone. Finally, there are calculators that plug into an electrical outlet through an AC cord.
Some people find that utilizing larger keys increases their accuracy. Other people find them cumbersome. Key size should relate to the comfort of the operator
