A rural teenager went to the market with a basket of eggs to sell. He added half of the eggs and sold them to the first customer. He added the remaining half and sold it to the second customer. Then he added the remaining half and sold it to the third customer ... When he added the last half and sold it to the sixth customer, all the eggs were sold out and all the customers bought whole eggs. Excuse me: How many eggs did the boy bring to the market?
How much is half an egg? This question seems difficult, but it's actually very simple. Through reverse deduction, the problem can be solved at once. It is important to think clearly that half of the sixth time can only be an egg. The backward reasoning method is simple and reliable, and it is a good method to solve the problem.
