Mathematics of VC Deal Valuation

This post by Brad Feld explains the mathematics behind some basic VC deal terminology, stating:

"I've found that even sophisticated entrepreneurs didn't necessary grasp how valuation math (or "deal algebra") worked. VCs talk about pre-money, post-money, and share price as though these were universally defined terms that the average American voter would understand. To insure everyone is talking about the same thing, I started passing out this document. Recognize that this is about the math behind the calculations, not the philosophy of valuation"
