Hi everybody, I hope I choose the right sub-forum! I'm reading Ricardo'sPrinciplesin their second edition, but I'm not good at maths. I would like to ask a thing about "present value".

What's the formula used to get 100 from 10 annuities of 16.27? And where should I put the "10 per cent" in the formula? In a few words, how would you explain the underlined sentence? Sorry for my poor English and thank you in advance!Originally Posted byMr. David Ricardo
