**Types of
Calculators**

While you might be able to perform all the functions of a calculator without one, calculators are convenient and can save you a great deal of time. Plus they provide you a more accurate result.

From basic calculators to graphing, scientific and printing calculators, there is sure a wide range of calculators available on the market that can compute basic and advanced functions. Here are few types of calculators that you will be able to find.

*Basic Calculator*

A calculator with limited functions that is usually used to perform general purpose operations. A basic calculator can support addition, subtraction, multiplication, and division equations. Most models can also compute negative numbers, percentages and square roots.

While a basic calculator offers the advantage of being accurate, fast and produce reliable answers, but they can only handle a limited string of numbers.

*Graphing Calculator*

A more powerful and versatile calculator with an ability to graph equations. Rather than just a row of numbers it features a full LCD screen that is dedicated to displaying multiple calculations simultaneously as well as display data in the form of graphs on x- and y-axes.

Because graphing calculators have a built in memory and are often programmable, they can often be connected to another calculator or a computer to share and transfer data.

*Scientific Calculator*

Available in a range of models – each varying in quality, features and price - scientific calculators have been designed to deal with scientific problems and compute statistical and trigonometric calculations. They are highly known for their ability to compute exponential and logarithms.

Similar to graphing calculators, these calculators are also programmable and can be connected to a computer for uploading of important functions. In addition, they can also be connected to other calculators to share and transfer data via a wired or wireless connection.

*Printing Calculator*

When compared to a traditional calculator, a printing calculator is a little different. That is because it has the added benefit of printing off every calculation entered on the calculator screen onto a roll of paper. This allows you to to double-check your work for errors.

When it comes to multiplication and division, the printing calculator works similarly to standard types. But when performing addition or subtraction functions, you will note that there is no addition or subtraction key. Instead, you will need to designate whether the number entered is positive or negative. Printing calculators are available in two basic types: an impact printing calculator and a thermal printing calculator. Each differs in its printing methods.
