At the arcade Dave had won 16 tickets. If he used 22 to buy some toys and 17 more to buy some clothes How many more tickets did Dave use to buy toys than he did to buy clothes?
Dave had 16 tickets. 
He used 22 tickets to buy some toys. 
That means he had 16 + 22 = 38 tickets in total. 
He used 17 tickets to buy some clothes. 
That means he had 38 - 17 = 21 tickets left. 

So, Dave used 22 - 17 = 5 more tickets to buy toys than he did to buy clothes.
