Correct. And now for a bonus mark, could you please, answer this question? What is the percentage increase since you bought your calculator in 2009 and now; compared to the percentage increase in average house prices over the same period?


Hardly the best deal of the century, I bought one for £5.50 from Tesco way back in 2009 when I was doing my GCSE's.


The FX83GT plus is £6.89. Basically, same as the FX85GT plus but without solar. Managed to get 6 for £1.40 each before they removed it from their website 10 mins after I placed my order.. Reappeared the next day for £6.89.

I agree. It has always been for a Pound.


This brings back the nightmare of maths class. "You'll need a scientific calculator" WE NEVER USED THE SCIENCE BUTTONS!! WHAT DO THEY EVEN DO!?


It's been this price for years, and is absolutely fine - but I'd spend the extra money for a better class of calc if I was using it often.

the one in your heart :3


Yeah £10 is about right it's often for sale for more than that but no one really buys it unless it's £10 or less :)


I bought the 85 in Asda Dyce a couple of days a go for £10. Not sure if that was a good price or not. Though its a good calculator.


FYI this model is not suitable for A-Level Maths anymore. You will need the new FX-991EX model. It's fine for other A-Level subjects or GCSE and lower.

What if the mortgage lender doesn't actually have that money to lend out, and mortgages are just based on your ability to pay?


Free but full of adds like most apps these days. Why is this a deal am I missing something?


I don't usually say this, but this is one app where the ads are worth it. He's done a cracking job on this. Also the ads aren't intrusive in my opinion, so ok.


To load all the adds that it pushes?

The Classwiz is more suited for A level college. I'd say the OP's calculator is better suited for GCSE O level high school. That said if you don't want the expense of having to buy 2, then by all means get the classwiz.


Good deal ..late for me as I had to buy one for my son two days ago and paid £13


This was briefly £1.40 last week but they removed the listing before I could post it on here.


There is a different, and superior calculator that is now recommended by many schools - and is approved for exam use. I managed to get one on Amazon for £15 a few months ago. Classwiz Casio fx-991EX. So if you don't actually need a calculator at the moment, but are buying ahead for secondary school or exams - personally I would wait and watch for the Classwiz to come back down in price. Certainly my son has found that it is superior to the normal Casio from Year 9 upwards.

I know it's not discounted but great price for high school x

I actually own 4 scientific calculators and yes Casio are the best not everyone can afford one. I'm a grown woman with house and children of my own. But growing up I was eldest of 11 so I would have been made up with this. I actually had to lend my teachers Calculator for my exam and I would have given anything for one of these. So yes Casio is better but for £1 Will help someone


I teach gcse maths, these are the worst calculator to use except for the basic four operations. The casio fx85 is the one to have and can occasionally be as cheap as £6


Diane Abbott uses one of these and she swears by it.


I would actually disagree with that. These are so awkward to use! And if you're not a student, you are better off using your phone.


Yes, they're fine if you're not a student. As the first two commenters have beneficially commented on.

I did think about this before posting and came to the conclusion that all evens including an odd hundred/thousand etc. (e.g.onE hundred and two, thrEE thousand six hundred, two thousand fivE hundred and four) will have an e in. When you then factor in that there are more odds than evens in numbers 1-9 then as the integer number series tends to infinity these big even numbers will dwarf the lack of even numbers with e's in the 0-99 range. I'd love to see a proper proof but as far as I can tell its pretty clear cut :{


prove it.


:o but so do the majority of even numbers :{


More suffixes, more cowbell, multiple decimal points, 'make your own' prime numbers, heard there's even a hidden easter egg if you type 80085. Totally NSFW stuff.


And more suffixes I hope.

This calculator is great for degree students in a budget as it will solve linear, quadratic, cubic...equations as well as carry out operations on matrices amongst other things. When you are solving 3rd order ordinary differential equation in an exam, this calculator might be the difference between a fail and a pass or even a higher grade. It is a time saver when you are assessed on your ability to solve differential equations. This price is standard and not really a bargain. Did not vote either way.


It's not that this calculator is very different. A Standard calculator works just fine but will be dependent on the student on how he uses it. This calculator makes things as easy as legally allowed. I purchased this for GBP 20 on Amazon. Brand New


I can tell you clearly aren't a maths teacher.


Graphical calcs are great for checking quadratics equations. Some now can transpose formula aswell as giving the working out. No good in an exam but great when you're learning on your own.


Both the calculators you mention are the ones that the my son's school recommend and sell.

What's strange about it being cheaper by buying direct from them? Amazon & eBay both charge selling/listing fees.
