That's because you weren't in dumb kid math. As a kid I was a seen as a trouble maker and put in dumb kid math. That was the best math class I ever took. They taught us how to balance a check book, how our taxes worked, interest rates and apr for loans and credit cards. I don't know why this wouldn't be a mandatory class for everyone. And maybe some of the skills like balancing a check book are outdated and that's fine. Update them with something more relevant now like how to read a contract or something.
