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:

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


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.
