This video tutorial covers the win odds and pot odds tools in Tournament Indicator Poker Odds Calculator and explains their use during live hand play. In addition, explained here are EV, Sklansky Hand Group Ranking, as well as the outs, position, and player indicators during a hand.
With Tournament Indicator you don't really need to know how to calculate poker odds as it is done for you, but if you would like to know the basic math behind it, there is also a short tutorial on calculating odds at the bottom of this page by Phil Gordon.
