We had a pretty big OMG moment a couple of days ago. During this weekend I was showing DS about numbers in different bases (base 2, base 16) because he's a patterns guy and similar to Kriston's DS. So I thought he'd like talking about why we have "digits" why we count in base 10, and how you could count with other symbols.

A couple of days later he went to his white board isle and titled it "1st grade binary" and started to write out 1 + 0 = 1, 1 + 1 = 10, 10 + 1 = 11, etc. I thought "oh he just memorized it" until he moved on to "2nd grade binary" and "3rd grade binary" with addition with carry over and subtraction with borrowing.

I am still shocked at that one.


"There are 10 kinds of people in this world. Those that understand binary and those that don't."
