Paco had 41 cookies.
He gave 9 cookies to his friend.
He ate 18 cookies.

We want to know how many more cookies Paco ate than he gave his friend. 

We can take away the number of cookies Paco gave his friend from the total number of cookies Paco had. 

41 - 9 = 32

Then we can take away the number of cookies Paco ate from the total number of cookies remaining. 

32 - 18 = 14

Paco ate 14 more cookies than he gave his friend.
