It needs to have:
n - (the number of data items entered into the calculator in a statistical calculation)
or s or - (sample standard deviation)
e x (or exp(x) or - (the exponential function)
inv ln or inv log e )
n! - (n factorial)

There are many different ways to use a calculator to work with fractions. THE EASIEST way is to think like a computer program. %Calculate all the formulas within the parentheses first and work outward from the parentheses. All fractions contain two values: The numerator and denominator. The Numerator is on top an Denominator is on bottom. The Numerator is normally placed as the Divisor value and the Denominator should be used as the factor. "What is 1/2 of 2/3?" question should be entered as (2/3) * (1/2)

Exponential and factorial functions are pretty much standard on any scientific calculator
The other 2 you mention will be on any calculator which can do statistical analysis
For example the Casio FX83ES covers what you need and you can get it from Argos for £6
As they say, other calculators are available. (From other retailers)

I've seen some 'cheapie' scientific calculators at Wal-Mart, K-Mart, and a lot of College Bookstores that do all that and a bunch more for under $20.

You may already have what you need on your computer.
From the start icon, go to All Programs, then go to
Accessories, and one option should be "calculator"
Most calculators have an option for "scientific"
and they will have all these special keys.
I just checked mine and it does have the special keys.
