A buying guide


Over the years, students, professionals, and even laymen have turned to calculators to work out difficult math equations. Graphing calculators are some of the best rated calculators because they are able to perform complex functions and solve intricate equations.

Trying to decide what is the best graphing calculator is a little more difficult than you may think though. As a general rule, a new graphing calculator can be quite expensive, but you can find used calculators relatively cheap. We have created this guide to help you decide which graphing calculator is the best to suit your needs.


Type of Graphing Calculator

There are two types of graphing calculators: Computer Algebra System (CAS) and a Non-CAS calculator. The Non-CAS calculator can compute regular numerical equations, whereas CAS calculators are specifically designed to handle symbols, create graphs, and solve intricate equations that you see in complex math courses such as trigonometry and calculus.


Determine the Use

When you are trying to decide who makes the best graphing calculator, you will want to take into consideration what the primary need is. If you are going to be taking advanced classes, you will want to get a graphing calculator that can handle the required expressions for your classes. If you are taking general math classes, you can get a basic calculator. Keep in mind that graphing calculators can create graphs, but they can also do formatting and use formulas. You also want to make sure that the calculator that you are looking at is accepted by your school.


Downloadable Information

Calculators are very much like computers and every so often you will have to update the programming. Not only that, you may run across a situation where the calculator does not have a particular formula or function. You may have to download the specific formula in order to complete your work. Some calculators use a USB to support this function, whereas others do not. Always choose a calculator that supports this function, because you never want to be stuck on a particular problem that could easily be solved—if only you had the right formula.


Graphing calculators are an incredible tool to have if you are in college or even to use as a working professional. You will be able to work out complex equations and plot information quickly and easily. By choosing the best graphing calculator, your courses will be much easier.

Texas Instruments TI84LUSSEPINK


I am recommending this model for girls who have the passion for numbers. While this can also be good for guys, use it only if you are prepared to take casual remarks from people who can see you. This is basically because the calculator has a bright pink color, even its sliding cover. In addition, aside from having the ability to store mathematical formulas and equations, it can also prove to be entertaining since there are some games that can be played when it is about time to take a break from having to deal with numbers.



Destined for girls, this is the perfect device to have if you are a science and math enthusiast who loves to stand out through geeky gadgets.
