What the... WHAT!

I came home and wanted to double-check Zach's homework.  To my amazement, what do I see but ALGEBRA.  Last I checked, learning Algebra in 7th grade was considered advanced.  When did this happen?

At this rate, they should be learning Calculus by 6th grade.  I better pull out my TI-82 calculator from high school... or is there an App for that now?
