Ease Of Use

Processing Speed

Check the RAM of your calculator. The higher the RAM the faster the processing speed. As a result, they are faster at performing mathematical computations.


Although 1-2 year warranties are standard, you need to double check to ensure that your calculator has one.

Amount Of Memory

Check your calculator’s ROM. Anything over 2 MB is a good graphing calculator that will hold enough data for your computations.

Solar Vs Battery Powered

The reason to buy one of the other is based on the practical nature. It’s a common nightmare for students’ calculator batteries to run out in the middle during an exam. We suggest getting a solar graphing calculator to prevent this issue from occuring.

Alternatively, you can buy a calculator that charges via a USB port. This allows you to plug it into a computer and allow it to become fully charged within a few hours. As a rule of thumb, get a solar or USB ran calculator so that you don’t have to worry about battery problems.

Calculator Apps

It’s the 21st century, almost every high end graphing calculator consists of apps to help you study more efficient. While these calculator apps are easy to use and are great learning tools, they do have one flaw. Teachers and testing exams tend to ban calculators of this nature.

Before you buy a calculator make sure you know if your school or examination site permits or prohibits it. This will save you money in the long run and helps you get a calculator that you can take along with you during your exam.


When you have to take your next exam or prepare for your next math class, a graphing calculator is a great tool to have by your side. And there’s no better graphing calculator than the Texas Instruments NSpire Graphing Calculator.
