 like algebra formulas like n equals 5. I look at that, and I said, what am I going to do with that? How do I apply that? And I thought, once I failed algebra in the ninth grade and took it in summer school, I got a C or a D, and I said, thank you, Jesus. And I had to have another math course to graduate high school. I took business math. My family owned a business. Well, I could understand that. That's managing money, balancing checking accounts, and so forth, you know.
