No more help guys?

Thank you, I'll have a read of that, I have a recommended textbook entitled measurements and their uncertainties, but it doesn't have any of this fundamental stuff in, I'm finding it really annoying! :(

After measurements, the following values and their uncertainties were recorded: x = 8.3 ± 0.1 and y = 2.72 ± 0.07 Find the following values of Z a) Z = x + y b) Z = x - y c) Z = xy d) Z = x/y e) Z = y/[(x)^0.5] (this is y divided by the square root of x) f) Z = exp(y)...

I havn't done this in a long time! And apparently I should know this easy, it sort of looks like a proof by induction, which I havn't done before and I am frantically trying to learn! Show that for each integer n the alternating sum of binomial coefficients: 1 - (n) + ... + (-1)^k(n) + ...
