Wouldn't get any scientific calculator besides the Casio ones.

Nobody really uses these and the functions can be quite difficult to get your head around, especially if all the teachers are using Casio's.

You are not allowed your phone for exams such as GCSE, A levels, City & Guilds, etc... So schools and colleges (especially schools) do not allow phones. Heat added.

This is a good calculator, we have one and still use it from time to time. I don't think it would have cost more that about £3 when we bought it (in someone's sale I suspect) so this is about the going price (never mind the RRP, no one pays that).

This certainly isn't a hot deal that people are going to dash out and buy (because they will almost always be able to get something similar for about the same or less) but it is a perfectly good item for next to nothing - what a wonderful place we live in.

It is a pity there isn't a 'lukewarm' button, because I'd have used it for this item, so I've added a little bit of heat instead.

Jeez ..just vote it hot! Honestly ..you want a lukewarm button??
I remember when I wer a lad, only the clever kids had these. The rest of us spent our time on our basic cheap Casio's, typing in all the car number plate style words we could think of.

With respect, that is a bit of a daft comment: the Sharp is perfectly easy to use for anyone able to understand (say) logarithmic functions (and if not why would one need a scientific calculator).

There is no apostrophe in Casios (assuming one is using it in the plural (as you were) and not in the genitive case).

It's a good calculator IMO and easily worth £3, but colleges/Unis I've been to will only allow certain models of CASIO calculator for examinations.

Judging by his username ending with 98, he's 19 and makes a fair point.... At schools and colleges pretty much all teachers use casios, and for stuff like statistics and other scientific calculator stuff, when they teach it they teach it using casios. Most of the teaching materials online for a level maths use Casio too......

They are on phones but I still prefer using a physical calculator. Even if it's just adding up a bunch of numbers, I prefer using my physical calculator if I can...... And no, I'm not an old guy who's out of touch with technology..

Well maybe, but I really dislike this dumbing down of maths through teaching by rote. The calculators will produce the same answers, so it is just getting used to the buttons rather than understanding what a function does. Any A level (or GCSE as long as it is the proper syllabus and not the foundation one) maths student should be able to adjust quickly between one calculator (or any tool: slide rule, log tables, computer program ...) and another.

If you are right about MAdam98's age then he needs to pay more attention in the English lessons as well as his maths!

Please spend an extra £3 on a Casio FX85, it is so much easier to use, and much more popular + solar panels so it is unlikely to run out of battery (I've had mine for 6 years ish)

Agreed, I have a TI and this Casio , the TI is more superior, however the Casio is the standard and using anything else will confuse the kids. The books are written with the expectation that the Casio is used.
I've never had an idea how to use these, but I do like typing numbers in and pressing the buttons to see what results I get. They're usually meaningless but it keeps my brain happy. Ooh buttons with heiroglyphics on them, must press them all.
If memory serves me right, with Sharps you can save a string of text / numbers in the memory banks of which there are several might be why these are sometimes not allowed in exams...
Used to be as valuable as iphone 7 in early 90s. Only the richest would have this. It was a like a mathematical computer in the pocket. Time is cruel but is Fact.
I remember these being about £20 and having to get one for a birthday present

Calculators are very commonplace in financials' trading floors. Independent piece of hardware = fast, always on accessibility.
I kinda feel sorry for all the other brands but Casio. I would probably only buy my kids a Casio for GCSE, as that is what the schools want them to use and all the notation is geared towards Casio Calcs. That's not to say this Sharp is all bad, in fact I quite like it and appreciate that it's got Base conversion eg Dec to Binary or Hex, something I used quite a bit when machine code programming (OK it was 30 years ago but hey ho). I cannot see this feature on today's Casios. DO I think it's an OK calculator - Yeah and hey it's really cheap! Should you buy it if you want conformance for the kids at school - I would probably pass.
I remember half ps and everything was.. 99 to make it appear more cheap! As to this how do they work out. 3 and all the hassle of giving change? Are they sure it is not 2.9299999999 ?

And
I wonder if some Countries still use an abacus?

Erm, I'm not a big fan of putting 99 after my name so I thought to use a 98!
Fair enough, my English grammar isn't what it used to be. (I do understand the difference between nominative, vocative, genitive, dative, accusative and ablative cases though!)

I can understand your viewpoint and to an extent agree however many students simply wouldn't bother to learn how to use a different calculator.

I do feel though that the Casio is the most simple to use.
My Casio was my best friend at uni. All my formula s and constant s were inside it for help in Maths and Physics
