Im new to this forum, just saying hi and am curious about something.

Although I done physics at school I haven't dabbled for a number of years now...Anyway, some friends and I were having a dicussion on various topics until physics popped up (2 of them are rather heavy into it). They wrote an equation down and asked if I new what it was...PV=C(1+i)n

I know I've seen it before but can't for the life of me remember it...Can anyone please help?

Physics has sortof peeked my interest again after 17 years so am curious as to what this equation is.

I know this is a maths forum but just thought you guys could help.

Thanks

Frizz
