Dave swam 6 laps and did 9 dives at the swimming pool. Crystal did 4 dives and swam 8 laps. How many more laps than dives did Crystal and Dave do?
Laps: 6 + 8 = 14
Dives: 9 + 4 = 13
14 - 13 = ?
Right.

To find the difference between the number of laps and dives that Dave and Crystal did, we need to calculate the total number of laps and dives for each of them separately, and then subtract one from the other.
Let's start with Dave:
Dave swam 6 laps and did 9 dives. So, he did a total of 6 + 9 = 15 activities.
Now, let's move on to Crystal:
Crystal swam 8 laps and did 4 dives, which means she did a total of 8 + 4 = 12 activities.
To find the difference between the number of laps and dives that Crystal and Dave did, we subtract the total activities for Crystal from the total activities for Dave:
Dave - Crystal = 15 - 12 = 3
Therefore, Crystal did 3 fewer activities (laps and dives) than Dave.
