Casio FX-CG50 Graphic Calculator (UK version)

This is my first graphing calculator and it is a great piece of kit. The User interface is easy to navigate. There are so many functions in the sub menus that you sometimes stop and think ‘I have used that before – where is it?’ but, after a few goes, it becomes natural. If you write down the sequence of keys that you use for common activities (e.g. Run-Matrix/Optn/Calc/SolveN), then you remember it after you have done it a few times. I spend most of my time in the calculator math mode and can move around the options now without really thinking. One strong feature is that when you input integrals etc, they look like they do in a text book.The graphing option is brilliant and it is straightforward to find the area under a curve, intersections, etc on the excellent colour screen. You can solve definite integrals either by using maths mode or by using graph mode – and you even get the same answer either way!One thing to note is that this calculator does not provide algebraic answers. If you want to differentiate x squared, for example, you have to do it at a value of x so it gives you a number – it won’t give you 2x. The same applies to integrals - they have to be definite. If you want the facility to get algebraic answers, you have to buy a CAS calculator – there aren’t many of those around as they are more expensive and generally not allowed in exams so there is a smaller market.It’s quite a big calculator (4AAA batteries in the back) and is very solid. Having originally thought that I would use it for specific work and use my smaller FX83 calculator for daily use, I now find that I use the CG50 for everything. One plus is that it displays all the calculations that you have done until you delete them – even staying on screen after the calculator has been turned off and on, which is really handy.One odd thing to note is that there appears to be no simple percentage function or key – the inbuilt one is rather complex. I am not sure why it has lost that when the cheaper models have it.There are numerous apps to explore – 3D graphs, spreadsheets – and they all work in a similar way so, once you have mastered one app, it is relatively easy to use another. Also there are lots of videos on YouTube taking you through solving specific problems if you find the manual a bit daunting.Recommended to anybody who wants to explore what modern calculators are capable of.

Before I bought this for my son I did research about this to see if it is allowed for GCSE plus for calculator it's high end price costing £118 but it is more expensive outside Amazon I found.It's has approval from exam boards which can be seen on Casio website.My son used the fx-CG50 said it's amazing it could understand maths better plus it has periodic table showing each element in detail. I asked my son will it help you better for GCSE maths, his reply was yes I think I will get much better grade with this calculator.Price I will say it is expensive 🫰 but if it helps to improve education by a bit it's cheap ☺️Quality is amazing on this it's colourful display.It has it own charging port to charge when battery life is low.Quantity of ways of doing maths is amazing showing graphs etc ...Weight is good too and efficiency of the product looks amazing 🤩Overall I would say it was an excellent buy to invest in my son future. 😃

The recommended version for A level maths and further maths at our school. Seems fine, however I would suggest getting one only if the teacher incorporates into lessons and the school has recommended as otherwise, it is really hard to learn how to use it! Helpful for the exam and allowed for A Level.

This is the big brother of the 991EX, looks similar with the carbon fibre finishing, although the key layout varies a fair bit from that model.First impressions out of the box are that it's a lot bigger than the standard Calc, and it used 4 'AAA' batteries, I would prefer a rechargeable battery, but I suppose this keeps the cost down. You get a USB cable in the box to update the CG50 and connect it to your PC.There are masses of functions here, including conic sections, graphing, Python programming even a Periodic table. It can be quite difficult to find things that were just keys on the 991EX, but after an initial panic, pressing menu 1 gets a standard calculation screen up.Its natural competitor is the TI 84 which is a bit more expensive in the UK (about £130, depending on spec) and the CG50 is superior to the TI84 as it's faster and with a better screen, although the price has jumped from up to £110 over summer.The CG50 has a great screen, and calculations persist between sessions. I'm impressed with it, having colour on your charts really shows up the lines well. It's a big jump up from even the £90 Casio b&w Casio calculator.So should you buy it? I think it's a great graphing calculator and will help any A level student to understand functions, graphing and Conic sections. I think it improves your chances, and some of the Pearson books have examples using this calculator. Recommended.

Good value for money. Good for A level Science and Maths

This calculator has many functions and you will not be able to go back to using a normal calculator after use. I also needed help and got feedback straightaway

Great value for money. Super functional. Easy to use, to bring.
