How to Choose a Calculator?

With so many calculators around, how do you know which one to choose? Learn everything you need to know about how to choose a calculator.

• Decide how complex of a calculator you need. Calculators start with the very basic addition/subtraction/multiplication/division combo, and go all the way to high-end 3D graphing calculators capable of solving complex engineering equations, but they fall into three standard groups: basic, scientific, and graphing. Choose one of these.
• If you chose the basic calculator, there's not much of an additional decision to make, as basic calculators are, well--basic. Scientific calculators, however, give you a few more decisions to make. Some include the ability to do not only basic trigonometry, but also many calculus functions (things typically included only in graphing calculators.) The most popular graphing calculators are made by Texas Instruments (TI). Whichever calculator you choose, visit the manufacturer's site, and compare the features of each version.
• Ask yourself how portable you want your calculator to be. Graphing calculators take up a lot more space than scientific or basic, but most graphing calculators can still fit in your pocket. If you'll be near your computer when you use your calculator, consider downloading one for free. Search the internet for free basic, scientific, and graphing calculators.
• Determine where you'll buy your calculator. If you buy online, you'll probably get a much cheaper price than in-store. Unlike other products like clothes, there's little worry that you won't end up liking the product, as you can view all the details and images of the product online. (Really the only risk might be not liking the way the keys feel when you press them).

How to Use a Calculator?

Using a calculator is an important skill for students. As they grow and progress through their education, they will learn advanced math skills that almost certainly require them to use a calculator. A few quick steps can help anyone use the device.

• Learn the symbols associated with math. Basic calculators are dominated by a few standard symbols including a plus sign (+) for addition problems, a minus sign ( - ) for subtraction, a multiplication symbol (x or * ), a division sign ( ÷ ) and an equal sign ( = ).
• Understand the processes that go along with the signs. If you don't understand the process of division, it's useless to know the sign because you won't be able to successfully put it to use. By learning basic math principles, you can then use a calculator to put those processes to work.
• Acquaint yourself with the layout of a calculator. Most calculators have numbers in the middle, beginning with zero at the bottom of the layout and working upwards, in rows of three, to the number nine. Basic math symbols are generally placed to the right of the numbers. You'll find the percentage button ( % ) and square root button with the math symbols.
• Try a graphing or scientific calculator when you learn more math processes. These calculators perform more difficult mathematical processes and can handle longer strings of numbers. When you learn various formulas and do longer problems, graphing and scientific calculators can do much of the work for you.
