Now Danica takes on the most feared of all math classes: algebra!

With Danica as personal tutor and coach, girls everywhere can stop dreading algebra and watch their scores rise!


In algebra, x can be anything: 12, -47, a billion—the sky's the limit. And by the time you finish this book, you'll be a master at solving for x and a ton of other algebra topics. But can you imagine if when we solved for x, we started by stereotyping it, shutting out a whole range of possible solutions? Like, "Hmm, I just don't think x could be a very big number; I mean look, it's so little."

I know it sounds crazy, but this happens all the time in life. The x you're solving for is your future, and it, too, can be anything. But you'd be surprised how many people stereotype themselves, shutting out a whole range of possibilities for their future. I almost did. Although I got good grades, deep down I believed that no matter how many A's I might get, it was only a matter of time before I would fail and the truth would come out: I just wasn't a math person.

See, I had an image stuck in my head of who could be really good at math—nerdy guys who would grow up to look like Einstein—and I simply didn't look the part. I mean, I'd been an actress on television since the age of 12. I almost didn't take a math class in college at all, because I felt so intimidated. Luckily, I love a challenge so I went for it anyway. It floored me when I actually excelled! Today I have a degree in mathematics, and I've written three books about math. Just like in algebra, the most satisfying answers are often the ones we least expect.

I'm here to tell you that giving up on ourselves because of our own stereotypes and limited imaginations is a far more destructive force than any challenge or obstacle "out there." Just like in algebra, attaining x can be very challenging—but that's part of what makes reaching big goals so satisfying and valuable. And how do we strengthen the "not-giving- up" muscle? By doing things that require determination and stamina, like algebra.

Algebra can be difficult at times, but believe me, it's not out of your reach—at all. In fact, it will shape you into the kind of person who embraces challenges in all areas of life. Stick with me; you'll see how algebra is just an extension of what you already know. And just like that, the incredible woman you'll grow into will be a beautiful extension of the strong young woman you're crafting yourself into today.

By conquering x, you too can be anything. And that's hot.

Personal Message From Danica McKellar

Ever experienced a brain haze? This can happen any time we are faced with something big and time-consuming that feels like an obstacle. It could be that you need to reorganize an entire drawer of beads that just spilled to the floor, or you have a math problem that you just don't know how to start. It's like the brain goes cloudy and wants to reject it: "This is way too complicated—never mind."

But these are the moments when you earn the right to become a truly successful person. Whenever you're confronted with a hard problem that makes your brain start to cloud up, practice thinking, "Wow, this looks challenging. It's a good thing I have me on my side." And practice feeling good as you say it. There are no "other" people who are more equipped than you to succeed in algebra or anything else you set your mind to. It's all about your attitude.

All the time you dedicate to strengthening your mind and attitude will serve you not only in math class, but also in your career and in all areas of your life. I am so incredibly proud of you!
