Calculators

Small electronic calculators have been around since the late 1960s and are now required in almost every business, large or small. They are useful for working with budgets, accounting, and other number-intensive business tasks. For larger projects, a spreadsheet on a personal computer is a better choice.

Calculators come in a variety of sizes and designs. Some have large LED (light-emitting diode) screens that can be used in dim light situations, and others use LCD (liquid-crystal display) screens that require good lighting to be seen. Some use solar power, while others use batteries or AC power from the wall outlet. Some are very small so they can be carried with you, while others are designed for desktop use. Some also have built-in printers (see Figure 8-4).
