In order to do basic addition, 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:

4 + 1 = 5
4 + 2 = 6
4 + 3 = 7
4 + 4 = 8
4 + 5 = 9
4 + 6 = 10
4 + 7 = 11
4 + 8 = 12
4 + 9 = 13
4 + 10 = 14
4 + 11 = 15
4 + 12 = 16


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.
