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:

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


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.
