2. Texas Instruments TI36X Pro Engineering/Scientific Calculator.

Texas Instruments TI36X Pro Engineering/Scientific Calculator

Here is a calculator designed for those situations where a graphing calculator isn’t allowed: your crotchety old Algebra teacher, certain standardized tests, and so on. It’s got many of the desirable features of a graphing calculator (equation solver, calculus features, and matrices) in the body of a scientific calculator. In addition to its ability to solve polynomial equations and systems of linear equations, there’s also an equation solver that will solve most other equations for x.

It offers multi-view to allow you take down various complex problems concurrently while displaying the progress and results of the different functions side by side. Its Math print feature shows math expressions, symbols, and stacked fractions exactly the way they appear in textbooks — so there is no need to adapt to a technical syntax. It also provides quick access to frequently used functions.

This calculator offers great functionality by taking advantage of the multi-tap approach which is so popular for alphabetic entry on telephone keypads: To obtain the different meanings of a key, just press it several times. The double-tap method is clearly superior to a separate shift key for single-finger operation of a keypad (every key acts as a shift-key for itself, so to speak, without a journey across the keypad). Other calculator designers have been wasting at least one shift-key by forsaking multi-tap.

Its data list editor allows you to enter statistical data in up to three lists, with a maximum of 42 items per list. Any list formulas that are entered can accept all calculator functions. It readily performs one- and two-variable analysis and displays six different regression models.

Nearly any algebra student will benefit from a calculator with natural math display. With this feature, the calculator can display formulas and equations in exactly the same way as they are written them on paper; which means fractions look exactly like fractions and also that you get to use full-size symbols. Having this feature will make reading the calculator easier, which is particularly useful for people new to using it.

Some calculators have high-resolution color displays that let you quickly see the difference between two similar graphs by formatting them with different colors. Only the most higher-end models offer full-color screens, with some even offering touchscreen capability. Full-color screen makes navigation of menus easy and graphs easy to read.

Processing Speed & Memory.

Two of the most important elements of algebra calculators are memory and processing speed. Different processors have different speeds, measured in megahertz (MHz). Fast processors let you perform and save equations quickly. Advanced calculators, especially CAS versions, typically feature faster processors. Many calculators let you save equations, solutions, and common problems for later using integrated memory. The capacity for each calculator varies.

CAS Calculator.

CAS means Computer Algebra System. When you buy calculators with CAS, that means you are getting an equipment able to solve equations, manipulate factor, variables, and more. Simply said, these calculators have the ability to solve problems with x and y, like x + y = 2x. When it comes to sophisticated calculations involving variables, these calculators are very usable. They are pretty effective in some circles, such as SAT, and many high school and college classrooms. A non-CAS calculator can only find numeric (which might be in decimal, fractional or radical forms) results. Before you decide to buy calculators with CAS or Non-CAS calculators, keep in mind your college testing plans, and your school’s math department policies.


Programmable models usually have all of the functions found in other calculators, but also let the user program functions, calculations, and applications. This functionality allows for great control and logic to be applied when solving complex calculations. These calculators can hold large amounts of data for the storage of programs and formulas.

3D Graphing Capabilities.

The 3D function allows the calculator to perform a variety of functions within the x-y-z area. You will note that most calculators have 2D capabilities at least, but 3D is quickly becoming the standard to look out for.

USB Functionality.

A USB calculator includes a data cable and USB port that lets users upload information. Simply plug the USB cable into a computer or laptop and transfer the information. Some have functions that permit USB connection with compatible devices for comparing calculations. Calculators with data collection and replay functions let users analyze completed hypotheses and graphical creations.

The best scientific/graphing calculators for Algebra 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 want to make sure your investment comes with a solid manufacturer’s warranty. While this doesn’t protect against things like damage caused by dropping the device, it does help you avoid having to replace a calculator that does not work because of a manufacturer’s defect.


Algebra is a headache. It keeps asking us to find X, and when we cannot find X, Algebra asks us Y. Technology gives us a better way to deal with Algebra, and since most learning institutions allow the use of calculators during exams students now find it less of a burden. If you have a few dollars to spend on your study, you will find this article helpful when you go out shopping for your calculator.
