Umm... actually I do a lot of math in my head. I was making my students' heads hurt just today explaining base other math (base 2, binary, base 16, hexidecimal, and just for giggles and laughs, base 12 just to show that the math works no matter what). It's a hard concept to wrap your head around if you've never done anything other than base 10.
Somewhat back on topic, look at what came home with me from
@CoturnixComplex ! Aren't they pretty? I'm keeping them separate until I can give them a proper intro to the rest of the flock starting Friday (close where they can see and hear each other, but separate) and hopefully integrating on Monday after work so I can keep an eye on them.
