Basic Calculators

There are many types of basic calculator, and each type is used for simple mathematical tasks, including addition, subtraction, multiplication and division. Students in math or science classes use basic calculators to speed up the process of solving basic problems, as do accountants for tax or expense purposes. These useful math tools solve percentages and simplify square roots, giving workers more time to focus on the job at hand. Basic calculators are available in portable or handheld models, but you can select more sophisticated desktop models for fast access during the workday.

Handheld Calculators
The most common type of basic calculator, handheld calculators offer extreme portability and fit securely in your hand and pocket. Handheld calculators are available in a wide array of colours and designs. These calculators feature easy-to-read LCD screens, and they save money on batteries thanks to solar power panels on most models. Elementary school students are typical users of handheld calculators, but adults also often use them in the home to balance the checkbook and create a budget.

Desktop Calculators
Desktop calculators offer the same functionality as handheld calculators; however, these calculators stay on your desk or table due to their size and power requirements. Some desktop calculators have more sophisticated features and incorporate tilt-screen displays. Ideal for use in offices or by accountants, desktop calculators have large buttons for ease of use and large displays that improve readability and show from eight to 12 digits.

Additional Features
Although basic calculators perform simple functions, some calculators have additional features, including buttons for profit tax calculation and metric conversion. Many basic calculators also have dual-power capabilities, feature eco-friendly designs and utilize simple memory functions, making them useful for performing more than simple mathematical tasks.
