That's why it comes back to math. Math has no bias. It doesn't come from TV. It doesn't know what you're wearing. Math treats all people equally. Especially when you're in a hard class with all boys, when nobody's cheering you on from the sidelines, when it's not "cool" to be smart, math is a nice thing to have. When nothing else makes sense, math reaches an answer.
