Why are we still using Calculators?

BUT, I really don't understand how phones have come SO far yet our calculators are STILL such puny, feeble, weak pieces of technology. Look at how far Qualcomm and Apple have come in ARM and TI is sitting here, using some garbage tier processor. Imagine what we could be doing if we had a Snapdragon or an A10 in a CX CAS. It's incredible that my $200 TI Inspire (which probably cost less than $50 to make) is decades behind some $200 phone with a 1080p screen and a half-decent Snapdragon processor. 

Because if you put a Snapdragon into a calculator with 4 AA batteries, you could probably expect a battery life of days rather than months.

 

Also calculators don't need that much performance. Most operations people do happen practically instantaneously on garbage tier processors.

Idk man. I mean, honestly, do you really need anything more power hungry and hot in a device which lives in students' bags and is literally used for one main thing? There's no need for higher end CPU's in a graphing calculator. It does its job very well, and quick at that. Anything "better" would eat up more battery, or even throttle due to lack of available power. It doesn't need anything more than that. Apple has lesser than great hardware in their phones compared to some Android flagships, but because Apple sat down and optimized their OS to work with the hardware it runs on, it doesn't really need anything better than what's out there now. That's kinda the same thing with these calculators. They work very well with what they're given. In fact, I just pulled out an old TI-30x to help me on some math homework tonight (have had it for literally 10 years) and it powered on right away, and did exactly as I needed in an instant. Keeping it simple helps to greatly improve reliability and longevity. Like the Willys GP, a very basic vehicle.

Refer to my comment about simplicity. Advancements in calculators would make them needlessly more power-hungry and expensive to manufacture. Especially since graphic ones are already far too advanced for the needs of any high school student.

Also, as a side note, Apple doesn't make processors. Samsung makes their processors.

Alright guys, I see your point - battery life, unnecessary performance and cost. I guess that the graphics calculator market being less than 0.01% of the smartphone market has made no reason for them to really improve anything. I just wish that someone came in and broke Casio & TI's dominance and did something about these things. :|

Really not much that can be done. You could enter the market and try to disrupt them based on price, but you'd be operating on much lower margins than they are which already puts you in a losing position, not to mention their already established brands, deals and even curricula that are based on them. They also already have their manufacturing, R&D and software already figured out, all things you'd have to spend quite a bit of money on before you even begin to make sales. 

Alternatively, you could simply chose to be a reasonable person and ignore anyone telling you to buy a graphic calculator and instead get a scientific one. This bad boy cost me like $10 and got me all through high school. I'm sure it's still alive in some drawer somewhere without a scratch on it. Those things were built like a tank.

It had a really nice back cover that slides out and onto the front, a very enjoyable mechanism that made me feel like a Digimon trainer with those Digivices you slide cards through from season 3. They also had plenty of space on them to customize with stickers, graffiti or even cheat notes. Definitely recommend. Obviously they can't "graph", whatever that means. But they do have functions like sin, tan etc and you can write or draw boobies on them, among other body parts and phrases. I'm pretty sure we never used more than 10% of their potential, if even that.

The calculators use a language called Ti Basic. There's a button on your calculator you press and it takes you to programming.

My super genius friend in high school had one (this was late 80s)..he wrote a multi-dice roller program for rpgs....was way cool :D (it was a simpler time).

what even is this thread?

 

"why can't we use PCs and Phone instead of calculators?" spoiler, you can, but not in school because of the very clear possibility of cheating.

Cheating is possible with programmable graphing calculators.  If a student knows what they are doing they can program it to solve just about any problem right through to a first course in differential equations. 

 

To my mind, if they are allowing the calculator they might as well allow a full blown computer THEN ASK HARDER QUESTION THAT REALLY NEED IT.

If they're that smart, the class is likely wasting their time.

Calculating without a calculator is difficult. Calculating with a calculator is easy. Even monkeys know how to use a calculator.

Okay folks, I understand: That math is hard without calculators and calculators are used to prevent cheating and programmable calculators can store data or solve problems that are not meant to be solved with a calculator which is cheating, And we pay money for the calculator software not hardware and we don't use our devices as calculators because the school don't have much time and money to install a copy of calculation software on every student's devices, And they put a weak hardware in it for power consumption, because the calculator's small battery could last more than 13 Years more than 70k Hours usage without being recharged, how amazing.

For us oldsters this thread is absolutely hilarious!  You guys don't know how well off you are with all the tech stuff, including calculators.  Back in the day we had to rely on primitive calculators and one had to interpolate results.  the primitive calculator that we all used (shown below) worked fine for every one of my chem, physics and math courses other than quantitative chemical analysis.  For that course we had to use five place log tables and countless sheets of paper were consumed in adding and subtracting as sample had to be analyzed in triplicate.  Any computer work was done on the campus mainframe in Fortran with punch cards.  the original DEC minicomputers were a godsend when I went to grad school and had a post-doc at Cornell even though they had far less computational power than cheap PCs.  I can still hear the rata-tat-tat of the teletype terminal that was hooked up to the DEC PDP-11!!

 

One of the best investments I made was a Hewlet Packard Programmable calculator (forget the model number as this was circa 1975) that you could do some pretty nifty work on.

That’s mad I’m in a chemistry lab. Can’t imagine how boring that analytical chemistry must have been. 
Simple tools are good, wouldn’t give up the calculator for a phone calc. 


Bleigh!  Ever hear of AC series?

I spent more than 100 Dollars on Calculator shit for my education, I am Feeling like it's not worth it when PCs or Mobile phones could do same operation.

I bought a used TI-84 w/color screen for $80 and sold it 4 years later for the same price xD

It was awful!!!  All of us had the CRC Handbook of Math Tables which I think is still published.in some form (I think my copy is in box in our attic; I'll need to go see).  I still have my old slide rule and when my daughter was taking pre-calculus in high school I challenged her to see who could solve a problem quicker.  I beat the TI graphic calculator!

a Physics professor pal of mine collects slide rules....like new ones, old ones, giant 3 foot ones.

Also for Calculators....calculators don't go haywire and do weird chat message things in the calculator app while you're trying to do math.

 

(I had a dream about trying to math on my iphone because of this thread)

You forgot that calculators are orders of magnitude more reliable than a smartphone.

 

A Ti-89 can survive a 5 foot drop on hard concrete. An iPhone can't. I've yet to see a calculator hard crash, I've seen plenty of phones and tablets needing a hard reset. etc. etc.

It certainly isn't imo either, however, it's what you can do with that little hardware. It's the software you pay for. Decades of research and development and these calculators can literally do things that most of us don't even know they can do. There's a reason that calculus classes require them.

When I took calculus a few years ago you learned to do things the hard way first before being able to use the calculator to do it for you. All in all calculus isn't too hard if you understand the formulas and how they're used.

Haven't read the whole thread, but it's horses for courses.  Some people love them for their size and portability others prefer a full PC/tablet.

 

Either way it's whatever you prefer.    I have an average calculator in my workshop (saves getting the phone out).   I like having access to apps that do more strenuous calculations automatically, however that is in the design stage not on the floor running. 


QuicK and DirtY. Read the CoC it's like a guide on how not to be moron.  Also I don't have an issue with the VS series.
