The 3 Fastest Calculators in The World - HP Prime ALL Versions!

[@calculator_boy]

Doing the operations in HOME rather than in CAS is one of the few ways to compare these, as they would all get the answer in milliseconds if in CAS, and with pretty much any integration or summation you throw at them. It is worth mentioning that in some cases, the first gen, revision A beats the second gen in CAS mode when doing certain algebraic simplification.

[@user-ghj3d8dgh]

Which is G2 model, 2AP18AA or G8X92AA?

[@eone199]

hp prime is the only calculator that still looks like a common calculator for me lol

[@franciscom656]

Hello. Is there less screen flickering in version D compared to the previous ones? I have version A and that problem on the screen is really annoying, when you move it you see those black lines due to the screen refresh. I don't know if it has been resolved in the latest version. Thanks

[@calculator_boy]

Indeed, the flickering is still present in Revision D, but it is much less annoying than on Revision A.

[@franciscom656]

@@calculator_boy Thanks!

[@gmcenroe]

My Hardware revision C has the light blue like your revision A so this has nothing to do with key colors. Up to C is G1 ; D is G2 version.

[@BreakingPintMedia]

Same, I have a G2 on order by my current G1 HW Rev C that I've owned since it first came out has the lighter blue (that is a PITA to see with my aging eyes).

[@notfirefly1290]

There are 2 hp primes rev C. The 2015 (light key) and 2016

[@razeliezerbenmoshe8052]

everybody say there is 2 generation of the calculator where did u get the 3 gen? how do u know wich is new

[@calculator_boy]

There are indeed 2 generations. Gen 1 has 2 hardware revisions, A and C. Revision C has the ability to work with a wireless dongle so it can be controlled by a professor during class/test. It also had very minor tweaks. Though both have the same processor, RAM and ROM, and perform the exactly the same speed wise. Gen 2 has only one revision, D.

[@franfernandez1850]

That's right, but impossible to find gen2 version D......!!!!!!!

[@animatoryGuy]

Hello! I have a question - I have the most recent version of the HP Prime but the Elements app is not on it. Is there a software update I need to install? Thanks! Your videos help out a lot

[@calculator_boy]

Elements is a 3rd party app. You can get it online or from another Prime that already has it.

[@daixtr]

I knew it, and am glad I made the right choice TI Nspire CX CAS II. The only aspect of the HP Prime I like is its premium feel and look of its keys. Apart from this, the "document system" of TI Nspire CX CAS II is lightyears ahead of HP Prime. Ask chatgpt which model do scientist prefer. Ask again which model do engineers prefer. My feel and my smell got it right all along ever since the beginning, that those who just prefer to add two numbers chooses HP Prime. But those, who are deep and those who have a long range week long scientific research calculations prefers the TI Nspire.

[@baquero766]

Engineers prefer HP Prime simply because its ease of use, fast speeds, and programmability, it does make sense for scientists to prefer more graphing centered calculators but that doesn't mean engineers are less deep or don't spend time on research, apart from that, if you don't know how to perform a calculation in the HP prime or cant find documentation on it simple write a program to do it

[@maxheadrom3088]

My Prime rev. C looks exactly like your rev. A - and just as unstable. The P/N is RMN HSTNJ-BC01. Do you know what's happening? Thanks!

[@calculator_boy]

Rev A and C are both generation 1, and have the same exact bugs and problems. The differences are that Rev C has darker shade buttons (blue and orange), and wireless capability using the official HP dongle via HP's connectivity software. Everything else is the same (speed, display, storage, memory, processor, software).

[@viscourtroy]

I THINK ver.C is the best!...

[@fahadahmed8889]

Where can I buy the G2 because all I found on amazon was the older models keep in mind that I do not live in the US and none of my local purveyors have it

[@calculator_boy]

eBay would probably be your best bet. Make sure the seller however confirms with you that it's G2, with a picture of the "About" page if necessary, because lots of sellers do not actually know for sure which of the 3 models they are selling (G1 rev A and C, and G2 Rev D).

[@fahadahmed8889]

@calculator_boy ya unfortunately I couldn't find anything on any website the closest thing was a post on amazon that had the model number of G2 but the pictures and description of G1 so I ended up getting a Ti nspire instead speed aside the note taking will be a big help

[@microcontrolecn5569]

Every HP Prime calculator has bugs problems or only a few part of production?

About the guy who complained about your video: he knows nothing! However, you should check where he's from because in most countries (AFAIK), calculator use in tests is prohibited. There's also the history of HP calculators - the company that made the first scientific calculator. In the early 1970s my father got the first scientific Ti as a gift from his boss and all the other engineers would flock to his office to play with it because at the time the only tool they has were slide rulers. I'm much older than you and got my 48gx around 1993 - and still consider the model to be the best HP ever made. I still use it and imho phone emulators are no substitutes for the amazing keys HP always used. I can do complex calculations pretty quickly using RPN and I don't have to pay much attention at thet key-presses because I know where they are and I always feel if I pressed a key or not - something we can't always know on touchscreen. I often do calculations in a professional setting that have to be correct so I not only have my original 48gx but also a couple of replacements. On his comment about 'why would someone do videos about old calculators' I would reply with other questions like 'why do people do videos about the Kurta? About the Hollerith machine? About Blechley Park or Babbage's Difference and Analytical engines? About the Sokoban? They do it because that's the history of technology and HP calculators were impressive technological advancements. Though nowadays all they do is provide a quick way to do quick precise calculations that can sometimes be somewhat complex, the history behind these machines will never stop being impressive. BTW, I would love to have a Kurta if ever get the thousands of dollars a original, well maintained one costs. (hope I spelled Kurta correctly. BTW, look for the video a guy made about his restoration of an IBM chesse cutting machine. It's IBM so I guarantee it will surprise you!)

[@calculator_boy]

You made very excellent points, and I agree with everything you've said including calculator apps on smartphones. I love the feeling of the keyboard on all my HP calculators more than my Texas Instruments. I have a friend with over 6K calculators in his collection (yes 6000. His office, garage and addict are full of calculators), and the 48 series is also his favorite just like most people. Though, my biggest dislike about legacy HP calculators is the lack of repairability ( The Prime has fixed that thank God!). They are nightmare to work on. Though they are well made and very durable, lots of model required keyboard adjustment after a period of use. I have 2 with that issue right now ( two 49g+ and a 49G). This has never been a problem with TI. In all fairness to HP, when a key stops working on a TI calculator, it's very unlikely to ever get it to work again. The display on most HP calculators can also be replaced. Only the first gen Nspire CX with the square battery cover from 2011 had a replaceable display. I replaced a few of those very easily. I probably have about 20 TIs right now in excellent condition but with bad display, which automatically renders the calculator useless. Safe to say that truly hate their decision for making a calculator obsolete as soon as the display goes bad. The casing and keyboard last forever on these devices; therefore, you would almost never need them even for parts. The display on HP Prime Rev A and C can also be replaced fairly easily. I've never opened a Rev D, but I'd think it's possible as well. P.S. No idea what Kurta is, but I'll look it up. I'll also give the IBM cheese cutter a look ✌😁

Hello, I'm Brazilian, and I'm studying computer science, I need a good calculator, could you help me by answering a question that I couldn't find the answer to anywhere, please? hp prime v2 or g2? which is better and what is the difference? I found your video very interesting and thank you for sharing this knowledge, maybe you think it's something small but where I live a simple calculator costs one or two months of work. thanks again.

[@calculator_boy]

The Prime v2 and G2 are just two terms that are used interchangeably. They both mean the same thing. However, G2 is the correct way to say it. "G" means generation, so G2 means Generation 2, which is the one you want because it's the latest Prime and the most stable one. Other important things to know: The Prime G1 had two different revisions, revision A and Revision C. G2 has only 1 revision, revision D

It is a D version and it says the software version is from 2020

[@calculator_boy]

All regions use the same software. You can easily update it to the latest 2021 software using the connectivity kit program. There are great forums explaining how to do it. Though, some versions of the connectivity kit program may not work (They'll keep freezing every time you launch the program. You may need to try different versions. Once you install a connectivity kit program that doesn't freeze, it'll automatically download all the necessary files for all 3 revisions (A, C and D). Simply connect your calculator to the computer and click yes to update it.

[@pelochobros7895]

@@calculator_boy I don't have the connectivity kit. Can I do it by just connecting the calculator to my laptop?

[@banderovetz1]

Unfortunatelly HP Prime doesn't operate correctly on polynomials over the field of real numbers. It is known, x^4+1=(x^2+sqrt(2)*x+1)*(x^2-sqrt(2)*x+1) and x^4-x^2+1=(x^2-sqrt(3)x+1)*(x^2+sqrt(3)x+1) Try factorize x^4+1 and x^4-x^2+1 by using factor() when "use V" ("use roots") and "exact" are checked in CAS settings. Do the same for x^2-3. Compare the results. If your HP Prime firmware is 2018 or newer, the calculator gives the correct factorization of x^4+1, but it cannot factorize x^4-x^2+1so far! TI calculators (89t, Voyage 200, Nspire) give correct results in the cases above. Try use tlin(sin(x)^3) (the example of tlin() from in-built help) when "simplify" in CAS settings is set to "maximum", "minimum" and "none". Compare the results. It turnes out, simplify() is inverse with respect to tlin(), but it wasn't mentioned in the users guide .

[@DanteAroniC]

HP50G can resolve x^4-x^2+1 too.

[@2L40K]

It appears, modern calculators are like computers, full of bugs. Will be interesting to see what results will give TI calculators on this polynomial: 1 + 16x^2 + x^4

[@eone199]

do you have the PROOF??

[@eeemuse]

For university (general engineering) which would be the better choice HP prime g2 or the Nspire CX II Cas? Regardless of what is allowed in exams. currently i have the Casio fx-991EX which was fine for my high school.

[@magzybogues9958]

HP Prime

[@bonjournito]

Can you solve sin(x)=1 and see if you get the correct answer which is 2kpi+pi/2

[@calculator_boy]

@bonjournito That answer is a general solution, so it's not wrong. Hp prime will just give you pie/2, which is also right, because it's the first occurrence of the equation sin(x)=1. 2kpie simply indicates all possible values.
