##### Fifteen children are playing hide and seek. One of them is the "seeker". After a while, seven children were still hiding. How many children have already been found?

##### Source - Math Kangaroo, Grades 3-4

**Solution:**

__Always summarize the question__

15 children are playing hide and seek.

1 is seeking

So 14 were hiding in the beginning

Now only 7 are hiding

So 14-7=7 children have been found

__Pitfall to watch out for:__

Most people forget the seeker when doing the problem. They think 15 people are playing, and 7 are still hiding. So 8 children are found. (Might seem silly but I've seen this happen all the time)

__Now try a similar question__

__Now try a similar question__

I'm waiting for a rollercoaster ride in a theme park. I'm the 14th person in a queue. There are equal number of people before and after me. How many people are standing in the queue?
