Math Question: There's a farmer who sells live chickens. He goes to three markets to sell them.
At the first market, he sells half of his chickens, plus half a chicken.
Then he goes to the second market, where he sells half of his remaining chickens, plus half a chicken.
At the third market, he sells half of all his remaining chickens, plus half a chicken. And he is left with no chickens.
How many chickens did he have at the start?
(HINT: No chickens were harmed at any of the markets, and they were all fully alive when they were sold.)
(Answer: 7 chickens)
