We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).
I'm surprised to see "Approved for Exams" featured so prominently, as handheld calculators for lots of standardized exams are being phased out.
All of the exams listed are either already offered in a computerized format or in a transition phase, with the PSAT, SAT, APs, and ACT all already offering Desmos in their testing apps.
I love handheld calculators, but, especially in a time-sensitive environment, it's hard to beat a large screen and full keyboard.
Show me a highschool math problem you can't do on a $12 Casio scientific like the classic FX-300MS https://www.usaofficemachines.com/csofx300ms-fx-300ms-scient...
There's even knockoffs of it for $1: https://www.aliexpress.us/item/3256809744184708.html
I picked one up when the 99 cent store was shutting down. It works fine.
Look what you can get for $20: https://www.casio.com/intl/scientific-calculators/product.FX...
TI is like the Intuit of the education world. I want to love them but this is ridiculous - a N4120 celeron laptop is the same price - it might be a garbage laptop but it's doing a heck of a lot more for your $160 than this calculator is.
Ti really needs to stop with the artificial product differentiation. There's no reason 15 years after the Nspire CX CAS came out that everyone of their calculators can't do CAS.
Loved it in university and still use it on my phone:
I learned to program on a TI-83 and later bought a TI-84+ with the cable that allowed me to transfer my apps and games between my device and other students devices. I have fond memories of hand typing into a TI-83 BASIC for hours using code I found online at the local library - games like Drug Wars and other similar choose this or that console based games. I would later get a USB cable that allowed me to download apps and games onto my device. Good times. Decades later and I'm still programming.

I don't see it. I compared a screenshot of one of these to a older T-84, and it looks like they have same number of buttons, and the buttons are just as cluttered (except the EVO has secondary labels on the keycaps instead of the case).
That's a good thing, since one of the best things about calculators is they typically have a ton of buttons for quick access to a lot of functions.
I loved my TI-84+ SE and wish I still had it (had all sorts of custom programs on it but it got lost or stolen before I finished high school).
That said, I find it really hard to believe that they can't provide better specs and feature set for the cost. User-available memory of 3.5MB is incredibly low, especially with Python support. These could be really cool handheld computers if TI put more effort into their devices that already have a massive install base.
Currently, most of their popularity in my experience is "lock in" effect from teachers who are familiar with TI calculators and lab / curriculum materials that are specifically built around teaching through TI calculators. At this rate they're charging a lot and resting on their near monopoly status in education, which I'm sure is very profitable for TI.
There used to be a great app called WabbitEmu that emulated these devices on Android. I think they got a cease and desist but it was pretty neat to have back in the day
Those who have used various classic HP calculators in the past may be interested in this:

These are clones of various older calculators.

Not as bad as I would've expected. Also, apparently it includes a very simple Python environment? https://education.ti.com/en/product-resources/eguides/eguide...

15 year old me in math class programming my loaned TI-82: CHALLENGE ACCEPTED!
The comments on this are fascinating. Although, I was waiting for someone to chime in with "HP is better cuz RPN."
2 dinners out for a family of four would cover the cost of this calculator. If my kid's school required this for math, I wouldn't bat an eye at purchasing one.
I needed a Ti-83 for school in 1996-1998. If you couldn't afford one, the school would loan you one for the semester. Band instruments were the same way.
I have no idea how on earth a scientific calculator costs almost as much as a cheap android phone. Do they use oled and snapdragon soc these days? Back in my school days a 20$ Casio seems more than enough.
There's the NumWorks which is very similar for a more reasonable price, that also run Python
How is the battery life? Rechargeable sure is nice, but the older models lasted forever on 4 AAAs (at least my TI-83). That's one aspect that would justify the low processing power for today's standards for portable computing devices.
What calculators are you guys using that aren't in academia anymore and don't need the "exam approved" limitations?
Or are we all just using software on our computers now.
That would be sad.
(I've had a Casio fx-991EX on my desk for a few years, that replaced a broken Casio fx-991ES. Though designed for academia, its operation is burned into my brain at this point.)
"Built to be a reliable learning tool, not a distraction"
They clearly haven't met a classroom of high school kids. Then again... I didn't have access to the internet in my pocket when I was in high school so....
It runs Python!
National exams will be wild for the kids capable of programming or vibe coding.
Hand reaches over and I lovingly pat the HP-67 sitting on my desk.
156MHz and 3,5MB user memory... Why do I feel like that is a joke these days.. I think some ESP32s are faster and have more memory, but not sure if they are fully comparable...
Interesting that this doesn't seem to include a computer algebra system like the Nspire CAS. Wonder if it's a testing environment compliance thing?
But can it play BlockDude?
Nice to see the hardware move forward. I still wish calculators were more open, or at least less locked into school-age pricing.
Distraction free tools like this calculator, is increasingly important to help keeping focus.
Genuine question, who uses these in practice? In my experience, calculators beyond the basic were always banned in high school and college, cause everyone's so afraid people might store something into them, and afterwards it's just matlab and python. It's not like laptops aren't a thing that everyone has on hand.
You will have to pry my TI-89 from my cold dead hands. I wish they still made it
And those goddamn displays still have the pixel density of a Tamagotchi.
What's the "online calculator license" ?
"Online calculator included (four-year subscription) •($80 value)"
75” 4k OLED screens would have been unobtainable when I first used a TI.
10yrs ago they would have been 4 to 5 figures.
Now they are what? A couple hundred?
How in the world is a TI graphing calculator still $160? These 30yr old calculator chips apparently hold their value like gold…
Biggest ripoff in academics.
There should be a cheap open source calculators for schools and exams. It’s ridiculous that TI is still charging this.
The race to run custom code on these is on :D
Is there any information on exactly what kind of processor is inside this thing? Since running python I'm thinking it's actually a low end mobile processor.
Looking at the price of this and other calculators, I wonder if there's a market for "dumb calculators" analogous to dumb terminals: a device with the calculator form factor, keyboard, and display, but where the actual computation happens on a paired computer/phone or a cloud endpoint over WiFi/Bluetooth.
It's a shame that maths in American schools is equated with calculation. All you need to be a mathematician is a calculator!

> 3x Processing Power - Matching one of the speculated options, the calculator appears to use an ARM Cortex CPU, finally retiring the z80 and ez80 family of CPUs that were used in three decades of TI-83 and TI-84 Plus graphing calculators. It's running at 156MHz, compared to the 48MHz of the older calculators. It appears likely that in an unexpected break from over 30 years of TI's operating system codebase, the OS has been re-implemented with new features natively on the ARM CPU rather than using an ez80 emulator to run an updated form of the TI-84 Plus CE operating system.
It looks like TI is finally moving away from the Z80. This must have been a pretty big engineering effort on TI's part. Like the article says, up to this point all of TI's low-end graphing calculators have been Z80 based and use the same system software that has a lineage dating back to the early 1990s. They were previously so wedded to the Z80 that when they introduced Python programming to their calculators, they did so by adding an ARM microcontroller that runs MicroPython, while the main eZ80 CPU acts as a serial terminal.
