WONDER WINNIE X + Y = SEXY thumbnail

Wonder Years heartthrob DANICA McKELLAR who played Winnie Cooper on the show, strips down to prove higher mathematics is more than multiplication.

Doe-eyed, soon-to-be, mom Danica got sexy in Maxim mag, posing provactively in lingerie, re-igniting her once adolescent male fan base.    

"I’ve always been really cautious about guys who have a Winnie Cooper fantasy and I’m so glad about that," Danica told the mag.

"I mean, I can count on one hand the guys I’ve been with. It was really challenging, but I never gave it up too soon, if you know what I mean."

Dana, who’s been married less than a year is a mathematician and her third book about the abstract science  Hot X: Algebra Exposed will be released late summer.

"Let’s make math fun and sexy and glamorous," Danica said.

"Smart IS sexy, that’s one of my main messages."

"It’s really cool when a guy tips 20 percent quickly and effortlessly so that when the check comes, he opens it and signs his name and done."
