Teach your kids to multiply with this cool grid trick

So now that I have a 6 year old boy, gill and I were talking about what its going to like when he hits high school and starts doing Friginometry and calculus. I don't know about you but I was horrible at both of those, never could figure even why I would want to have to figure it out, go figure that one eh.
So we were thinking maybe start brushing up on our math skills in preparation for that horrid day when the home work comes home. You know do a math course or what ever.
NAH F8ck that just google it!!
So we or rather I did, Now this is why I LOVE GOOGLE so much. Its stupidly helpful, and always provides relevant results for your search queries
