Paco had 41 cookies. He gave 9 cookies to his friend and ate 18 cookies. How many more cookies did he eat than those he gave to his friend?
Paco had 41 cookies. He gave 9 cookies to his friend. 

That means he has 41 - 9 = 32 cookies left. 

He ate 18 cookies. 

That means he has 32 - 18 = 14 cookies left. 

He gave 9 cookies to his friend. 

That means he ate 9 + 18 = 27 cookies. 

The difference between the number of cookies he ate and the number of cookies he gave to his friend is 27 - 9 = 18.
