A right brainer!
Actually, I'm both side brained and I always thought my logic side was a bit stronger.

I figure if you're just doing a lot of equations, that's just a bunch of plug n chug and it means you can follow a process. I don't see that the same as understanding it, and understanding something means you can see it, or even feel it. I hate equations cause it's just abstract nonsense - I have to get a feel for what the equation means, usually trying to figure out how to do something without an equation first. Then I can deal with the equation - even though they're still abstract nonsense. I'm still seeing the "logic" of it, not a pretty picture at a museum.

Do you think I could sell that picture for a lot of money if I called it Scarlet Concepts in Dancing Probabilities?
