2
=
1
 
      
-
    
=
  
 
   Chocolate Box   MediumBlue Box   DarkCyan Box  minus     Chocolate Box   MediumBlue Box  equals     DarkCyan Box

We start with three boxes, take away two boxes, and now have one box. We take away two boxes from our three boxes to get one box.


Here's another example:

In order to do basic subtraction, you must memorize some equations but fear not: FoxyMath will help you! When you are finished with this lesson, you will know the following equations:

  2 - 2 =   0
  3 - 2 =   1
  4 - 2 =   2
  5 - 2 =   3
  6 - 2 =   4
  7 - 2 =   5
  8 - 2 =   6
  9 - 2 =   7
10 - 2 =   8
11 - 2 =   9
12 - 2 = 10
13 - 2 = 11
14 - 2 = 12


The following exercise will help you learn the above equations and what they mean. Please take your time: take whatever time you need to learn the material.
