I'm terrible at math. I still use my fingers to add things together, and I barely passed my high school algebra class with a C (I got a 75...).
Then in college I took a "Math in Society" class. AWESOME! We learned how to calculate electric bills (like how much does it cost to keep X amout of appliances on for X amout of time), and we learned about fallacies and all kids of useful stuff that I've actually gone back and used outside of class already. I pulled a high B in that class (Like an 88 I think). Our teacher was a jerk, but the material was fun!
