Scientific Calculator

Advantages: Easy to use, reliable, batteries last AGES!
Disadvantages: No solar panel to back up batteries

...I first got this calculator when I was 13 or 14 years old. Our maths teacher told us we needed a scientific calculator and although I already had one, it was different to the one the teacher had. The teacher told us we could buy one through school and this way we would all have the same calculator. Normally it wouldn?t bother me if I was different but in this instance I wanted one the same, as calculations are sometimes worked out slightly differently on different calculators. I love this calculator and have used it happily in many lessons and exams since I first bought it. ~ What is a Scientific Calculator? ~ A scientific calculator is a more complex calculator than the usual calculator you may use. Scientific calculators support mathematical functions such as trigonometry, statistics, algebra and scientific notation. ~ Why...

Oregon Scientific DP-200

Advantages: Motion sensor, Radio controlled, Bright projection
Disadvantages: Cost £85 - £100, Radio signal dependant on weather

...I have been using a previous Oregon Scientific projection clock for the past couple of years, and I have been very pleased with it. I decided to get this model because one of the main points is that the projection is strong enough to be seen in daylight. Even on a really bright day, it is still possible to see the time on the ceiling or wall, unlike previous models. As with previous models, it has the radio controlled time feature, meaning that it is always up to date, and requires no manual changes. Although it is possible to turn the radio signal receiver off, and do it manually. This may have to be done if you are using it in an area of weak or no signal. With this clock, it has a switch so that it can be taken anywhere in Europe, and it should continue to work. The clock also came with an outdoor temperature sensor which...

The Fantastic Sharp Scientific Calculator

Advantages: great added features including memory storage
Disadvantages: not the most advanced calculator you can get

...i am sure that most of you know what a calculator is and you have probably used one aswel. but not everyone will know what the difference is between the ones with the fancy names right? even thought i am meant to be telling you about the scientific calculator i think it is a lot easier to understand the difference if i first explain other types of calculators you can buy. there are many different types including the standard calculator, the printing calculator, the graphical calculator and of course the scientific calculator. so what is a calculator used for? a calculator is basicly to help you out with sums. it is very effective as it is quick and also very accurate. all you need to do is type in what you want it to work out for you and it will instantly display your answer on its screen. this is very quick and will save you heaps...

Cool Calculations in Chemistry!

Advantages: Very useful, lots of practice questions
Disadvantages: Only in black and white, expensive

...-level course and contains all the information on the types of questions based around calculations. I have looked all over the book and I can't find which specification it is for so I assume the calculations in A-Level chemistry are pretty universal over all the major exams boards. (I am with AQA and the majority of the book is relevant for me.) The book is split into 11 chapters - from chapters containing basic formulae to chapters with more difficult aspects of chemistry. Each chapter has information about calculations including worked examples complete with model answers. This gives information about when you would use these calculations in chemistry as well as showing you how they are done before giving some problems for you to try. There are answers and some worked solutions at the back of the book, which help you check your progress...

Scientific Calculator alot of features

Advantages: range of features on it, dual powered

...I have had this calculator for 2 years and it has not dated at all, it is a scientific calculator which is solar powered, but also battery powered. There are many modes on this calculater including; Basic Arithmetic - COMP Complex Number calculations - CMPLX Standard Deviation - SD Regression Calculations - REG Base-n calculations - BASE Soultion of Equations - EQN Matrix Calculations - MAT Vector Calculations - VCT It is very easy to use and displays what sum you have typed in appove the answer, handy if you want to double check important figures, without having to type it again. It has all the scientific functions you need and they are very clear on the buttons. You can also do metric conversions on it too. It comes with a lid which slids behind it when in use in front when not in use to stop it getting scratched or random...

Simple to use scientific calculator

Advantages: Easy to use, can edit lines, remembers history, suitable for GCSE
Disadvantages: None

...This Canon calculator is fantastic. It is powered by batteries and solar panel and is simple to operate. There are many functions including a number of memories, they are labelled as A, B, C, D, M (Memory) and X and Y. The X and Y are probably really useful for GCSE and A-Levels since everything seems to revolve around X and Y in those questions! You can edit lines and go back to see what previous calculations you have done - useful for double checking or seeing where you went wrong. This is certainly a good calculator for GCSE use (it seems to do everything I covered in mine including sin, cos, tan as well as cubes and square roots, pi and fractions). For A-Level it doesn't have some of the more useful functions, there are no imaginary numbers, for example. But the bulk is here and I would strongly recommend it...

Oregon Scientific DS9300 - Get what you pay for

Advantages: Price, Extras
Disadvantages: Performance, Robustness

...My Experience? I've had the Oregon Scientific digital camera for around 2 years now, and overall I have been disappointed. However I have a little relief in the fact that I paid very little for it through a TV bidding channel, Bid-up TV, I recall that it was about £100 along with an array of free image editing and gallery software. Ever since I received the camera it has gone down hill consistently. I know others have had good experiences with this camera, so it would appear to be on an individual basis, but do take heed. Also as other owners have reported the camera will often freeze on random occasions. To resolve, remove the batteries and replace them, this usually makes the camera work again. Even the slightest little tap will crash the camera and it will turn off. Schematics? The camera has a very simple, conventional...

Casio Calculator

Advantages: Good Price, Does that it says it will, Solar powered
Disadvantages: None that i can think of

...I bought this calculator at my local woolworths as i was after a scientific calculator and one that was cheap(i paid under £10 for this one which seemed a good price). The calculator is made by Casio which are a well known brand for making anything from calculators to TV's . The dimensions are 84x155x12mm and it is a light too which is a bonus. The keys are large enough for most people and all the writing is clear on and above the keys. This scientific calculator with has 249 functions (164 scientific functions) - including statistic functions. It is primarily aimed at secondary school student but i reckon it will be fine for almost any function unless you need the functions of a graphic calculator It is solar powered so it doesn't require any batteries in order to function however as with all solar powered products,you just...

Review of Casio FX 85 ES

calculating success!

Advantages: Thoroughly useful if you are studying maths!
Disadvantages: It is a little pricey.

...The Casio fx-9750GII is one of the newest releases in the graphical calculator range from casio, as you would expect from such a large brand its almost faultless! The calculator comes standard with a 3 year warrantee which is helpful considering the price! The calculator comes with 64kb RAM and also has a USB port so you can connect it to your computer. If you havent used a Graphical calculator before and you work with more complex maths regularly i would definatly suggest investing in one, and this is a top of the range model. As with most standard scientific calculators it can convert from fractions to decimals, calculate simple and complex multiplications divisions etc.. but as this is graphical it can do just that little bit more, it also has a very clear icon menu. The Icon menu clearly shows each available main function...
