Top 20 Best Scientific Calculators 2021 Reviews: Why we hate TI and love the HP
There are two types of calculators you need in university: graphing and scientific. And they’re both probably going to be Texas Instruments calculators. TI Has a virtual lock because back in the 1990s they won out with blessing of the various college entrance exam boards and all of the teacher training they offered. Schools needed to settle on a single standard and TI was the one that won out over Casio. HP didn’t really care as it was focused more on the professional market with their GX models. This is why your 1997 TI 84 calculator is virtually unchanged to the 2021 model. Look at laptop from 1997 and realize it has less computing power than my bathroom scale.
Perhaps this is needed. Teachers already have to put up with cellphones and all of the requisite rudeness they bring to the classroom. Do we need to have the SAT board make rulings about calculators having cameras, WiFi, speakers, etc? In fact, one of the reasons TI won over the competitors was because they’re too simple — anything with a QWERTY keyboard resembled a computer which scared the bejesus out of academic types worrying about cheating. Once all of SAT’s friends were jumping off a cliff, why not SAT board themselves?
Now that TI has this lock on the industry, offering affordable options is no longer needed to offer a functional business in the educational calculator space.
As for Casio…well, let’s put it this way: Casio calculator’s are for the person who roots for the underdog, the person who looks at a Toyota or a Honda and decides to get the Kia.

The Nspire line by TI is the modern answer to HP’s 48GX, only 25 years too late. Some of the biggest deals are the backlit screen. Lots of other TI models used just a simple LCD display. For most university classes, this device is going to be overkill. You can probably get it to solve things like differential equations for you, but hopefully the teachers already know this.
Texas Instruments TI-89 Titanium Graphing Calculator
WELL, here we have it. 30 years of ‘innovation’ for learning summed up as TI’s answer to the TI 83, also 25 years too late. Good features are things like pretty printing of functions as well as symbolically simplifying algebraic equations. This also means you get rational numbers out of some functions, such as sin(60) coming out to ?3/2 instead of 0.86603. Tl;dr: Jingoistic elevator music.
HP G8X92AA LA Prime v2 Graphing Calculator
Well, here we have it. HP’s offering. It’s wonderful. It can do so much. Like the HP48GX of yore, it can be programmed. Unlike the TI-8* series, this features the innovation that Ti has avoided. And you know? We have to look at the HP’s innovation as being a fault. The HP Prime series isn’t approved for any AP or SAT/ACT exams. Elsewhere in the world, use is approved for other nation’s exam programs. You can expect a 15 hour runtime on a single charge from the 1500 mAh batteries and features a Computer Algebra system (CAS) based on the open source Xcas package.
HP 50g Graphing Calculator
You’ve probably noticed by now that I’m a bit of an HP48GX fanboy. More on that in a minute. This HP50 is the direct descendent from that line. This calculator is also programmable. The CAS system was open-sourced back in 2003. The loving, reassuring arms of RPN entry mode await you, letting you know you can be as weird as you want with it. The world of algebraic infix notation doesn’t understand you. HP50’s RPN mode will. Would you like to program your calculator? We’ll let you do that, here are the tools. Here’s an RS-232 port that you can use to talk to other calculators. There’s even an IR port — probably the most reliable and easy to use communications port I’ve ever run across. Press-button, aim, let run. Modern computing can’t accomplish that. The wireless printer in the office is always throwing a chit-fit about not being able to be found or this SSID not being found.
You don’t know what having this device meant back in the day. It was a statement, a work of art, an assurance of technical superiority over soft-skills like product-market fit. You’d lend it to a friend and they’d feebly type in ‘2+2’ and the calculator would beep an error at them. You’d get smarmy, roll your eyes and press in ‘2 2 +’ and watch their entire view of the world evaporate to be replaced by shame from their ignorance while their mind was trying to sew together fig leaves for loin clothes. It’d be like showing one of the US Founding Father’s a casual day at the Folsom Street Faire.
That was the dark side of the HP48GX. The sense of superiority that the calculator conveyed. Now that the decades have passed and those students have graduated and moved on, they can only remember this calculator not for what it could do, but for what the surly owners were like. The device itself was forgotten.
HP discontinued the HP50 in 2021.
Texas Instruments TI-84 Plus Graphics Calculator
Yeah, I kinda have to mention this one by federal law. It’s the TI 84. It’s approved for all use on ACT, SAT, PSAT, and AP exams.Ultimately, TI realized that they were in a double-sided market, like the text book industry. Students paid for it, but they didn’t select the TI. The various exams did. It was this insight that lead to TI being dominant in the industry.
Your high school and college teacher received training with this calculator. They can show you how to do y=mx+b or calculate the integral of an odd function over an even interval. We hate the TI-84 because it’s a sort of enforced conformity. The TI-84 represents The Man, the TI-84 is the Blue Bill, the TI-84 is your practice girl from high school that you settled down with, didn’t leave your home town and got a cubicle job. Imagine if this was how you were forced to use computers for simple things like email or text. Terrible, but safe.
