She is smart and sexy, she is fantastic role model.

Her second book Kiss My Math: Showing Pre-Algebra Who's Boss is also out.

here is a little bit about her School life from wiki:

McKellar studied at UCLA, majoring in mathematics. While at UCLA, she became a member of Alpha Delta Pi sorority. She graduated summa cum laude in 1998. As an undergraduate, she coauthored a scientific paper[6] with Professor Lincoln Chayes and fellow student Brandy Winn. [7][8] Referring to the mathematical abilities of his coauthor students, Chayes was quoted in the New York Times[9] as saying, "I thought that the two were really, really first-rate."

As a result of her role in the publication, McKellar has an Erd?s number of 4. Because she also has a Bacon number of 2 through her acting career, she is one of the few individuals with a finite Erd?s–Bacon number; in her case, 6.
