 How Subtraction Works
  A beginning subtraction lesson using sets for kids and parents to work
  through together (page 1 of 3)

This is the very beginning of understanding how subtraction works.

Let's look at this set:

5 triangles

Count how many triangles
are in this set...  There are 5!

Now, take two triangles away...

5 triangles with 2 being taken out

3 triangles left the 2 triangles that were taken out

 
Count how many triangles are left
in the set... 
There are 3 left!
 

So, 5-2=3
