[quote=Etcetera] You said expression. It's just an equation with no equal sign.I was going to learn Python when I had time. [/quote] The second time I was supposed to say Expression, I said Equation. I'm only supposed to understand what changes in one side of an equation will do to the isolated value on the other side. Cool. Also, Turing machines are awesome. I can't believe I didn't know about them earlier.
