A little help please u wonderful people!

Its my own fault because i didnt pay much attention during A-Level maths

But could anyone tell me if there are any formulas for working out how much money i will have if i have a set compounded interest rate over a certain period of time?

E.G I start with £1000 and interest compounds at 10% how much will I have in 10 years time

If someone could help me by letting me know how i find that and how i work backwards as well, would be much appreciated!
