We all know Winnie was a great student on The Wonder Years, but the real-life Danica McKellar has turned inspiring math whiz!
McKellar has found huge success in her best-selling math tutorial series Math Doesn't Suck: How to Survive Middle School Math Without Losing Your Mind or Breaking a Nail and her more recent Kiss My Math.
McKellar co-authored a paper with a professor while attending UCLA to prove a new mathematic principle, the Chayes-McKellar-Winn Theorum.
She then went on the tutor math on her website.
McKellar says Kiss My Math means, "Um, excuse me, I'm going to do whatever I want with my life, and I'm sure as heck not going to let a little math get in my way."
Finally, a healthy addiction for a former child star.
