You may or may not remember the show that aired in the 80s and 90s, “The Wonder Years.” If so you must remember the lead female, Winnie Cooper the longtime young love of the show's male lead, Kevin Arnold (Fred Savage). Winnie Cooper was played by Danica McKellar, who instead of continuing a career in Hollywood chose a different path. Mathematics.

Not exactly everybody’s favorite subject, Danica McKellar went from a career in Hollywood to earning a summa cum laude degree in mathematics and later contributed to the creation of the Chayes-McKellar-Winn theorem.

Now Danica is taking her love of math and using it to help boost the self-confidence of young girls by writing about it. She has just released her third book on the subject, “Hot X: Algebra Exposed."

McKellar's earlier books included, "Kiss My Math: Showing Pre-Algebra Who's Boss" and "Math Doesn't Suck: How to Survive Middle School Math Without Losing Your Mind or Breaking a Nail."

“There are stereotypes that have been out there for a long time that tell girls that their main asset, the main thing that they are valued for, is their appearance and also that it's to the exclusion of anything else," McKellar told CNN.

"My goal is to have the girls get through their math classes and then have the confidence that comes from feeling smart and knowing you can do it," she also said. "Math is like going to the gym for your brain. It sharpens your mind."

When she’s not acting, creating mathematical theorems and writing to help inspire young girls, she’s preparing for the upcoming arrival of her first child.

A big shout out to Danica McKellar our SheHero of the week and her message that girls can be anything they want to be.
