Wow Dottie, you have opened whole new worlds today. I was always pretty good at Math...but knew nothing about this binary and base system stuff. I just found this cool site that has lots of cool links on it. I am excited to see new stuff that DS5 can learn as he is soaking stuff up pretty quick. I showed him square roots, exponents, and plotting yesterday on the x,y axis as he found it on one of computer things. After a brief explanation...he got it and got them all right. It's crazy.

Here is that site I just found if anyone is interested. It looks pretty cool. Well, cool for DS that is. "cool" is relative.
