Danny collects bottle caps and wrappers. He found 46 wrappers and 50 bottle caps at the park. Now he has 21 bottle caps and 52 wrappers in his collection. How many more bottle caps than wrappers did danny find at the park?
First, we need to find the total number of bottle caps and wrappers that Danny found at the park. He found 46 wrappers and 50 bottle caps, so the total number of bottle caps and wrappers is 46 + 50, which is 96. 

Next, we need to find the total number of bottle caps and wrappers that Danny has in his collection. He has 21 bottle caps and 52 wrappers, so the total number of bottle caps and wrappers is 21 + 52, which is 73. 

Now, we need to find the difference between the total number of bottle caps and wrappers that Danny found at the park and the total number of bottle caps and wrappers that Danny has in his collection. The difference is 96 - 73, which is 23. 

We can say that Danny found 23 more bottle caps than wrappers at the park. 

Therefore the answer (numeric) is: 

23
