When I was in school Marchand, my teacher told me that you only needs to know where these paris payments: $ 10, 15, 25, 35 and 75. Remember them. 10 is 15, 15 is 22.50, 25 is 37.50, for 35 years it is 52.50 and 75 is 112.50. the rest breaks only one. As for 125, you know that 100 countries, 150, 37,50 and 25 countries. This would make a bet of 125 paid 187.50 …. to 315, you know 300 pays 450 and 15, 22.50, for this, just add Overall, this 315 would pay 472.50 as one that helps is still paying 2.50 learn 4, because sometimes one additional bet or 2.50, not knowing what to do with a chip to 2.50. Hope this helps!
