Paul got a box of 5 crayons for his birthday. During the school year he lost 9 crayons while he gave away 33 crayons to his friends. How many more crayons did he give to his friends than those he lost?
Paul got 5 crayons. 
He lost 9 crayons. 
That means he had 14 crayons left. 
He gave away 33 crayons. 
That means he had 47 crayons in total. 

Now we can solve this equation: 

5 + 9 + 33 = 47 

That means he gave away 33 crayons.
