Price

No matter how much this calculator costs it is worth it, this is because these calculator are used nationally(KS2, KS3, G.C.S.E's) in the United Kingdom and therefore if any issues do arise then a G.C.S.E student could ask his/her friends or the teacher. A brilliant thing about these calculator is that they extremely cheap you can grab one of Amazon for a £10. From ebay you are able to purchase the never version (Casio FX83 Gt Plus) for £6. So no matter which way you look at it these calculators are a bargain.

Ease of use

Yes, you get an instruction manual, but I believe that it is useless, this is because these calculators are so easy to use. For example if you brought it to use the simple calculation (+,-,*,/) then you just need to use the bottom half of the calculator. And whenever you press a button the screen will tell you what you pressed to ensure no typing errors were made. On the case there are simple instructions in case you forget key formulas or equations however it must be noted that the cases are not allowed to be taken in to a G.C.S.E exam. The scientific calculations will only be used if you understand the function; therefore anyone who uses the scientific part will have the knowledge and understanding and therefore should find it straight forward. Furthermore if you make a mistake or want to see a previous figure then you can just press the replay button and that will just show you your last figure providing that you did not press AC. Also using the powers button on this calculator is very simple as it shows up on the display clearly(*10-)The buttons are fairly large and therefore having large fingers should not be an issue. The calculator is very compact and subsequently prefect for pencil case and rucksacks.

Functions

There are 249 functions on the calculator but the mains ones are:

• Add,minus,divide, multiply
• Store and recall numbers. When woking out long equations this is very usefull as you don't have to write down the numbers. All you need to do is press ShiftRclA and this will save the number in A and to bring the number back all you need to press is RclA
• Sqaure/cube numbers and their roots.
• Surds
• Fraction that actually show up as fraction on the screen! Unlike other calculators.
• Sin,Cos,tan.o
• Brackets

Conclusion

Overall, i would recommend this product to everyone; unless you are studying above G.C.S.Es as you would need a graphical calculator. The caluclator has an amazing battery life, as i have owned mine for 4 years and only changed it once (1 AAA battery). The calculator is easy to use and therefore is perfect for student and a general all rounder calculator.
