conversations.value: If there are 3 goldfish, and each is playing with ten red balls, then the number of red balls in the tank is 3*10=30
  There are also ten platyfish playing with 5 white balls, there are 10*5= 50 white balls.
  The total number of red and white balls in the fish tank is 50+30 = 80
