Currently there are 28 children playing. Until a moment ago, 4 of those 28 werent there. To find out how many there were a moment ago, we have to exclude those 4 kids that just came — or subtract the number of kids that just came from the number of kids currently playing.

28-4=24

We can check: 24+4=28
