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. 

This means that he has 41-9=32 cookies left. 

Then he ate 18 cookies. This means that he has 32-18=14 cookies left. 

Now we need to compare the number of cookies he gave to his friend with the number of cookies he ate. 

9<18

This means that he ate more cookies than those he gave to his friend.
