Scientific Calculators

There are many types of calculators; one of the most common is a scientific calculator designed to handle scientific problems. The calculators can range from a few dollars to several hundred, depending on the quality, features, and model. The calculators are helpful for advanced mathematics aside from scientific features. Modern scientific calculators have a programmable ability with formulas and functions that you may need for certain classes. These functions can be handy for complex scientific formulas like physics, chemistry, and advanced mathematics.

One of the best things about these calculators is the ease of use while maintaining a good amount of functionality. Parents can buy one of these calculators for their children in middle school classes and late elementary classes. Due to the simplicity, older students may want something more powerful if they plan to keep using the calculator for longer in higher education. However, depending on the seller, the TI 30X IIS and Casio FX-300ES Plus are not identical.

You can access the functions on these calculators by pressing one or two buttons which is very common. The display also looks modern, even though they are not as fancy as those in graphing calculators. Other essential functions like sin, cos, tan, exponents, logs, and more are available. The FX-300ES Plus is available in two variants, the original and 2nd edition. Both models have different keyboard layouts, and the 2nd edition has an NTD feature missing from the original calculator; the one we are discussing here is the newer model.

TI 30X IIS and Casio FX-300ES Plus Design

Like most calculators, the TI 30X IIS and Casio FX-300ES Plus are plastic. The build quality is not superb, but it is understandable from the price point. The original FX-300ES Plus has a glossy finish around the display, while the 2nd edition has a matte finish and boxy shape instead of the curvy one. The TI calculator adopts a classic design that looks chunky, but it feels sturdy. The calculators come with a sliding cover from the same material. Both calculators also use a solar panel to power the unit.

TI 30X IIS and Casio FX-300ES Plus Display

At this price point, the TI 30X IIS and Casio FX-300ES Plus are excellent choices. The two have a two-line display; the top line is where you will type the expression, and the result is shown at the bottom line. This system works well to help read the more complex things you may enter on the display. The difference is that FX-300ES Plus, especially the newer edition, can show the fractional and radical form of the number instead of decimals and exponents. If you want this feature in the TI calculator, the TI 30XS MultiView is also a good choice.

TI 30X IIS and Casio FX-300ES Plus Functions

Simplicity is one of the advantages of TI 30X IIS and Casio FX-300ES Plus; what you see is what you get. These calculators don’t have a soft menu where they hide other functions, making the two pretty easy to get familiar with. You can see the keyboards to check what the calculators can do. Of course, you can do all essential functions like sin, cos, tan, exponents, logs, etc. You can also type extended expressions and let the calculator evaluate using the order of operations. You can even scroll the FX-300ES Plus to see the previous inputs.

TI 30X IIS and Casio FX-300ES Plus Features

The most exciting feature of these calculators is the Natural Textbook Display from FX-300ES Plus 2nd generation. This feature is present in many other Casio FX series to show the answers and entries precisely as they would appear in a textbook. You can see fractions in templates with one number above the other and powers with a smaller number in the top right corner. Older calculators often miss this feature, but it becomes more common in the more modern choices as it helps read and enter expressions much more effortlessly.

In addition, both calculators also have an essential statistical function. The difference is that FX-300ES Plus is more capable and can do more than just the standard deviation. The Casio model has three primary functions; Computation, Statistics, and Table. The Stat function can perform various things, including linear regression, and there are at least eight different options from the menu. The interface is not the best, as you must go back and forth, but getting used to the calculator is not impossible.

TI 30X IIS Vs Casio FX-300ES Plus

TI 30X IIS and Casio FX-300ES Plus are good for the price, but the new Casio is more expensive than this TI calculator. The simplicity is an advantage, but we can’t shake the thought of 30X IIS being outdated nowadays with many modern scientific calculators having better displays and systems, including those from the company. The main difference is how these calculators type the input and show the result because the FX-300ES Plus 2nd generation has NTD. This calculator also has more functions stored in the different modes.
