Texas Instruments TI30X Pro Mathprint Scientific Calculator

Parfait!

Let's get the deducted star out of the way. This calculator is overpriced. There are vastly more powerful and faster graphing calculators (like the Casio fx-9750GIII) that cost less. If it were priced more reasonably, like the functionally equivalent Sharp EL-W516 or the Casio FX-991, it would get its full 5 stars. Some may not know this, but TI marketing critters played around with its calculator names. This calculator is just the most recent version of the TI-36, replacing the TI-36X Pro, but they decided to rename it to TI-30X Pro. How this is supposed to make the calculator more attractive is something that only the twisted mind of a marketing person can grasp. MAYBE, it's a deception to allow the calculator in environments that allow calculators only if the have TI-30 in the name (most that accept the TI-30 also accept the TI-36, but it may be different in Europe, where this new model is primarily sold). That said, the improvements over the TI-36X Pro are subtle, but significant. The TI-30X Pro is noticeably faster and sports a much more readable high definition black-and-white LCD screen that also has much better contrast and less reflection. The solar panel is larger, and presumable provides more power. They new keyboard uses squarish keys, whereas thee old one used rounded keys. That applies also to the arrow pad. The new keyboard feels crisper, but the old one feels more firm. This is subjective, but I find the new square arrow pad to be more ergonomic than the old oval one. Aside from that, the keyboards share the exact same layout, which is normal because they're just two generations of the same calculator. Is it worth upgrading if you already have a TI-36X Pro? Honestly, no. All you get is a prettier and slightly faster calculator that's otherwise exactly the same as what you already have. Is it worth buying if you don't already have a calculator? It depends. If your school (or professional exam) requires this particular model, you may not have a choice. If you do have a choice, you can get equivalent functionality (and in some cases, more) from Sharp EL-516 and Casio fx-991 or fx-115. Any of these would be an excellent choice. And the older TI-36X Pro is still available at a fraction of the cost of the newer model (depending on the day, it can be only 1/3 of the price!), so that's a perfectly valid alternative as well. But if you don't mind the price and you're a fan of TI calculators, the TI-30X Pro is nice.

This is the fastest, function rich and most user-friendly non-programmable scientific TI-calculator you can get. The speed is on par with my old Casio fx 2.0 and the ARM-based HP-15C CE. It works the same as other similar Texas Instrument calculators. I bought this one because it gives the exact answer in fraction form by default. And the screen is very nice to read from. I also like that it has a huge solar cell to save on batteries. I wasn't prepared for how large the calculator would be. It's noticeably larger than my smartphone and almost as large as my 20 years old graphing Casio calculator (see photo). If you actually want a small and pocketable scientific calculator get the Casio fx-82 Solar II. Texas Instruments could probably shave off a cm from each side if they tried.
