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.
