3u: MIF, supplemented by a bit of jones/couchman, excel and coroneos, but dont use them too much
4u: D&G Arnold's book prior to it being published by cambridge (+ excel)

Does any one else use this bk?(its published by Edward Arnold)
Has it been updated in the cambridge version?

(ie if u hav seen both bks)

we use maths in focus...yes it is by far the easiest but i think its ideal for the basics.... the examples are easy to understand and then u can go onto supplements

I use Maths in Focus. My teacher hates it a lot. So he usually just gives us photocopies from mostly Coroneos, past papers and other random places. I think Maths in Focus is way to easy, and is a waste of money. I'll be glad to get rid of it.

ok

i think you forgot to add an ending term for part (a), otherwise it looks like it goes to infinity

For non-negative integers n and r: n_C_r = 0 when r >=n; meaning it cancels out beautifully.
