Danny found 27 bottle caps and 25 wrappers at the park. 
Now he has 36 bottle caps and 29 wrappers in his collection. 

We want to know how many more bottle caps than wrappers Danny found at the park. 

We can find this out by subtracting the number of wrappers he has now from the number of wrappers he had at the park: 

29 - 25 = 4
