Graphing Calculator Review GuideAs every student knows, math can be confusing. After learning the basics of math, a student enters algebra, geometry, calculus, and other divisions of math that use intricate formulas to arrive at an answer.

While the best understanding of advanced math is obtained by learning these formulas and remembering key concepts, there are some problems that can’t be solved without help. And just as WiFi speakers make audio easy and WiFi extenders make internet networks easy, graphing calculators make these formulas and key concepts easy.

What is a Graphing Calculator?

A graphing calculator is an advanced calculator that is used in high school and college level math classes and by professionals in math-heavy careers. These calculators perform basic functions like addition, subtraction, multiplication, and division, but they are also able to do many other functions. This includes calculating formulas, calculating and plotting graph data, and computing equations that contain variables. For extra information, check out this guide on how to use one of these calculators.

These calculators are used as a tool to help students learn advanced concepts in math, and they’re also great for checking work that’s completed manually on paper. A graphing calculator features all of the functions found on a basic calculator, as well as those found on a scientific calculator, with additional functions for graphs and complicated equations.

What are the different types of Graphing Calculators?

There are quite a few different types of graphing calculators on the market, although most have the same basic functions. While shopping for one of these calculators, keep an eye out for these types to determine which one will best fit your needs.

Color screen – Most graphing calculators have a basic black and white screen. However, there are a few modern models that feature a full color screen that makes navigating through menus easier, and it also provides graphs and information that is easier to see.

Alkaline battery-powered – These calculators use alkaline batteries for power. These can be more convenient because if the batteries are dying, you don’t have to worry about using a charger, and you can simply replace them with spare batteries. The downside is batteries are an extra expense.

Rechargeable – You won’t have to worry about using alkaline batteries in these units, which can be charged with a power cable. While you save on purchasing extra batteries, you do have to make sure you have access to a power outlet if your battery is running low.

What are the advantages of owning a Graphing Calculator?

With a graphing calculator, you can better understand many difficult mathematical concepts found in geometry, algebra, and other high-level math courses. While the calculator doesn’t do all of the work for you, it does make it easy to check your work and really nail down the key concepts that are taught in your course.

Who are the contenders for Best Graphing Calculator?

Considerations for Choosing the Right Graphing Calculator

If you or your child is in an advanced math class, you’ll find that a graphing calculator is an invaluable tool to have. It is important that you select a calculator that performs the functions needed for your math course, is easy to use, and fits all of your needs. Before you buy, take these four considerations into mind to ensure you’re fully satisfied with your purchase and get the most from your new calculator.

Graphing calculators are not cheap, and you should expect to pay anywhere from a minimum of $50 up to several hundred dollars for one of these units. Consider your own personal budget, as well as the features you need before making your decision on which to buy. You want to ensure that the calculator you purchase not only fits your budget, but also provides you with everything you need for your specific course.

You don’t want to have to squint at the screen to see the answer, so look for a high-resolution display. For the best viewing experience, look for a full-color display. The one drawback over choosing a color screen is that units equipped with this feature are typically much more expensive.

Battery type
If you are always on the go, choose a model that uses alkaline batteries, and make sure to pack spares in your backpack. If you don’t want to deal with the hassle and expense of changing out your batteries, a rechargeable model may work best for you.

As mentioned before, graphing calculators do not come cheap. You always want to make sure your investment is fully protected with a manufacturer’s warranty. While these don’t protect against things like damage incurred by dropping the device, they do help you avoid having to replace a calculator that does not work because of a manufacturer’s defect.
