CasioCasio fx-991CW Advanced Scientific Calculator (UK Version)

had one originally but the display broke as it was launched into tarmac (dont ask) but otherwise was very durable: It was so good at its job in the ~year I had it and did so much that I bought a replacement the same day I broke it. Truly the best calculator on the market for GCSEs (and even A levels) + incredible value for money. I recommend trying one out before you buy one as (with any calculator) it takes time to adapt to it and learn everything it can do but it's a great investment and has so many useful modes, levels, tables, etc

Take the time to download the user manual and view some of the on-line tutorials. Requires some set up and configuration. Multi-function keypad layout takes some getting used to. Will need to invest some time to get the most out of the advanced functionality. Nice scientific calculator, excellent value. Would have liked a more positive key action.

The media could not be loaded. Perfect calculutor for GCSEs and hopefully for Alevel maths too! It really helped me get that 9 and its solar powered so no need to charge it. Its very compact and build quality is good, with much more extra features like solving quadratics for you which are gery usefuls. around ~£25 you wouldnt find a better calculator.

Perfect for year 7-10,

Very usefulWorking well

Perfect for the job

I was shocked when I saw this product! It’s almost thirty years I didn’t use this kinds of calculator. It’s so complicated and great functionality. The size is good to put in my daughter’s school bag. If the seller can provide a introduction video for the beginner that would be helpful.
