MediumPurple Box   CadetBlue Box   DarkViolet Box   SpringGreen Box   MediumVioletRed Box   Empty Box  minus     MediumPurple Box   CadetBlue Box   DarkViolet Box   SpringGreen Box   MediumVioletRed Box  equals     Empty Box

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

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:

5 - 5 =   0
6 - 5 =   1
7 - 5 =   2
8 - 5 =   3
9 - 5 =   4
10 - 5 =   5
11 - 5 =   6
12 - 5 =   7
13 - 5 =   8
14 - 5 =   9
15 - 5 = 10
16 - 5 = 11
17 - 5 = 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.
