Here's another one:

Look at this set:

9 circles

Count how many circles
are in this set...  There are 9!

Now, take five circles away...

9 circles with 5 being taken out

4 circles are left the 5 circles that were taken out

 

Count how many circles are left
in the set... 
There are 4 left!
 

So, 9-5=4
