Style Name: FX-85GTPLUS Black
I bought this scientific calculator for my 15 years old daughter in preparation of her GCSE. It seems to be quite popular with that age group. They knlow exactly what they want and it serves them well for their purpose. There is another model of this calculator, however this model is more desirable due to the additional power source from its solar panels built into it. She is quite pleased with it.

About 4 months ago, I decided that my previous calculator needed updating (quite an old Casio model) & wanted to find a scientific calculator suited to A level examinations. Although i must admit, the Casio FX-85GTPLUS was not the calculator I originally wanted to go for. I ended up buying the Casio FX-85ES after reading various reviews & the price was very reasonable. However, I received through the post the Casio FX-85GTPLUS model instead...Emailed the company I bought it from, & they explained that the FX-85ES model was discontinued/out of stock.
I decided to keep this calculator and boy am I glad I did!

Firstly, I found the calculator very easy to use... the buttons are very clear & I liked the fact that Casio have added the orange AC and OFF buttons..adds a bit of colour to the calculator! I presume it will attract a lot of young teens or those studying for their GCSE's/A levels :)
The calculator also does a lot of the work for you... the calculator has the ability to change decimals into root form which comes in handy, & I find the fractions button on this calculator a lot easier (and quicker) to use than on my old calculator.
The Casio FX-85GTPLUS is also solar-powered which should make it very long lasting!

However as I said previously, the calculator does all of the work for you, so for me (an A level Maths student), it's quite easy to become dependent solely on your calculator to convert e.g. decimals into fractions, when really it should be application of your knowledge of the work as well. Also, the plasticky, cheap feel of the calculator might put some people off..

I would still definitely recommend this calculator to anyone... although I think it's definitely geared towards GCSE/A level students more than anything.

This is perfect for my A-Level maths and further maths but would be great for GCSE work as well.

I bought this to replace my old Casio which I've had since school, 25 years ago! Has all the same features as my old one & a few extras plus a nice big LCD panel. A great price & quick delivery!

Casio calculators have been a great benchmark for many years unless you're an advocate of HPs with reverse polish logic-I never got to grips with that, and have used Casios for over thirty years. Texas Instruments devices I've had access to haven't been relevant since the early TI30 was thrashed by the Commodore 9190 over thirty years ago (where are Commodore now ?), and Sharp occasionally produce a passable Casio-like device. I use a Casio 9700 graphics (at least fifteen years old) most of the time, but this is a very good back up, ideal for exams where I can't use a programmable and has been ideal for my children's schoolwork. Lots of really good functionality and presentation ability.

It overcomes a serious problem of logic- which I admit Casio disputed- with its predecessor, where 10/3Pi came out at about 10, by dint of its inserting an imaginary * between the 3 and the pi to give 10/3*pi or (10/3)*pi, or about ten. In fact, it should have inserted parentheses to give 10/(3*pi) or about 1. Be warned ! Now one of my standard checks if I'm presented with a random calculator anywhere. Thankfully, the GT plus has overcome this, and gives the right answer, otherwise it would get -69! stars.

As it is, a really good little product. Maybe I'd like a bigger battery but the solar cell is really effective and so this hasn't been a problem.

Oho ! Now I see some people are struggling with the Calculator's logic. Well, there's an easy answer to that- calculators have used at least five different logics over the years; I've owned ones with four, avoiding RPN. The trick is to see what it does and understand what you're doing; also, read the manual, and have an expectation of the answer; most errors are obvious.

I am realiably informed, by the son I purchased this calculator for, that this is THE ONE to use for GCSE Maths - well at least at their school. So he's happy and I'm happy and a very good price to boot!

"A Prime number is a natural number that has exactly two (distinct) natural number divisors. For example, enter the value 10 e.g. 10 = 2 x 5 and the calculator provides the relevant two number answer."

Obviously 10 is NOT a prime number, so what went wrong here? Somebody overlooked the significance of the word "exactly" in the above definition of a prime number; it should be taken literally, so "exactly two divisors" means 2 divisors, not more, not fewer.

We can see than 10 has exactly 4 divisors: 1, 2, 5, 10.

Exactly four divisors is not exactly two divisors, hence 10 is not a prime number.

In the example quoted above the calculator has returned the prime factors of 10 (of which there are two). This is not the same thing as saying that 10 is a prime number, which it isn't. 2 and 5 are both prime numbers, since they each have exactly two factors, themselves and 1. 1 itself is not prime because it does hot have two factors.

The calculator itself is great. But I would urge any student to be familiar with how to reset the calculator to factory default settings, especially if they rely on a calculator provided by the school in their exams. Another pupil will doubtles have messed with the settings, which can lead to unexpected behaviour (from the calculator - sadly the behaviour of the offending pupil is probably all too expected)
