This has been unbelievably useful as with the many functions, it helps with things that would normally take a long time to do by hand.
It is a white colour with a green back and sides. The lid is easily taken off and can be put on the back whilst the calculator is in use and the large screen is incredibly useful when looking at graphs.
It came packaged in quite a large box ( 20cm x 14cm) and althouh the calculator is quite bulky, most of the box contains the instruction booklet. It is 480 pages long with ALL of it being in english. This meant it was a bit daunting to look at so I only really used it
to work out how to put the batteries in.
Pressing on will take you to the main menu which has 15 options: 1)run 2) stat 3)MAT 4)list 5)Graph 6)dyna 7) table 8)recur 9) conic 10) equa 11) prgm 12) tvm 13)link 14) cont 15) mem
So far we have not used all of the functions so I will just tell you about the ones I know
~Run~ This is like a standard scientific calculator, with it being possible to do both simple calculation and by pressing optn some more complex ones. This mode is probably one of the ones I have used the most on here. It is possible to store numbers on here for future refence as a letter. This is particularly helpful when a decimal number is required further on in the calculation. Also, by pressing shift F6, you can switch between to the graph mode, making it easy to view a graph while working out calculations. All button on the calculator are laid out well and are clearly labelled.
~Stat~ This mode is mainly used for statistical calculations involving probability. The first screen shows a with 6 columns and as many rows as it neccessary. The good thing about having 6 rows is that you can have different calculations at the same time without having to delete one. Once the data is inputted into the table, calcullations can be made to find lots of things automatically such as the mean, standard deviation and the range. By pressing the dist button, it is possible to work out normal, binomial and chi squared distribution easily.
~Graph~ This is probably the most useful function, allowing you to input an equation to draw the graph. The graph does not appear automatically, instead appearing as if being drawn, something that amused me and my friends for quite a while. The trace button allows you to find out where a particular point lies on the graph. There is quite a lot of memory on this calculator allowing up to 20 graphs to be drawn simultaneouly.
~Equa~ The equation funtion is another useful one which allows you to input an algebraic equation in and it gives you the solutions. I found the solver function hard to use at first, not realising it was neccessary to press execute multiple times. It also solves simultaneous equations without the long calculations.
~Prog~ I don't know much about the programme mode however I have seen other people use this to create games. So far I've seen a simple version of snake and ping for two people. I would love to learn how to programme my calculator like this but I just don't have the computor knowledge!
~Mem~ Last one I'll discuss is memory. This is basically where you need to go to reset the calcuator. Doing so will delete all stored data and reset the functions to default. This is quite useful if I think I've messed it up some way or a friend ha just pressed all the buttons in a vain attempt to draw his name.
This calculator has got quite a good battery life, with my friends lasting her more than a year. I changed mine in paranoia before an exam but i'm sure they would have lasted as long. Unfortunatly, the calculator is not solar powered and does not take kindly to rechargeable batteries, lasting about a week with them fully charged. It is quite robust as has not broken even after quite a few accidental dropping. Although the calculator is bulky, it is actually surprisingly light (unless I've just got used to its weight) and the screen is a good size. The batteries are easy to put in with the battery cover being easy to remove, but not so easy that it falls off.
It has 32B of memory, which doesn't mean much to me but it seems like a lot and I've not had an out of memory message yet.
I bought this calculator for £30 through the college however it is alot more expensive on amazon (£48.90 at the moment)/
Overall I would definately recommend this calculator for anyone taking maths or stats past GCSE as i have found it invaluable so far and I'm sure I will in the future. Although it is quite expensive it is worth the money, simply for the amount of things possible.

My God, how calculators have changed since I was last studying. An impressive review there in a clear, concise and well structured format. In my view worth an E.
