As a writer, I agree with you. I am horrible at math. In my life 2x3=5 most of the time. If I had to suffer and fail at Calculus when I can't multiply some days I would certainly start writing books about evil scientists abusing a village for its resources and then have the village revolt against its scientific masters with pitchforks. Throw in a great protagonist and a love interest and I have a bestseller with possible international movie rights.
