I see questions quite often for the quite simple formulas so i thought i'd gather them in one post. Hopefully some of you can have some use for it. Also posted some examples for them to see how they are used. If there is something missing or any misstakes, please let me know.
Mathematic formulary for poker.
Odds:
(unknown cards  outs) : outs
Pot odds:
(Pot+Bet):Investment
Implied odds
Draw odds  pot odds = implied odds needed
Equity to call bet:
EQ=Bet/(Pot+2*Bet)
Pot odds <=> Equity
x:1 => 1/(x+1)=EQ
1/EQ1=x => x:1
EVCalculations
( EV= P(1)*$(P(1))+ P(2)*$(P(2))+…+ P(N)*$(P(N)) )
Calling a bet:
EV= P_win*(Pot+Bet)  P_lose*Bet
Fold equity:
EV= P_fold*Pot + (1 – P_fold) * (EQ * Total pot – Investment)
Purebluff FE, EQ=0:
EV= P_fold*Pot  (1  P_fold)*Investment
Tournament maths
Mfactor
M=Stacksize/(bb+sb+Ante*Players) *
Effective Mfactor
EM = M * (players/10)
Effective Big Blind
EBB=2*(bb+sb+Ante*Players)/3 *
*A little trick is to replace (bb+sb+Ante*Players) with (Pot before any action preflop) for calculations on the table.
