random math lesson: how to calculate the payoff from a parlay.

First, convert every bet into a factor. If its +, then divide by 100 and add 1. If its -, divide 100 by that and add 1.

(e.g. +105 -> (105/100) + 1 = 2.05, -110 -> (100/110) + 1 = 1.909)

Then multiply your bet by each factor, and subtract your bet.

x=bet; A, B, C = factors in a 3-way parlay; y = what you win.

(x*A*B*C) - x = y
