Andrew doing more Math!

A few weeks ago I posted a video of Andrew doing addition.  At the end of the video I jokingly said "subtraction is next."  Little did I know that he would really want to learn it and pick it up so quickly.  He has already informed that I need to teach him to multiply next!  Again keep in mind he is 4 years old and still has another year of pre-school before he starts Kindergarten.

My little Genius!
