About

Shortly after I signed up for MSE, my profile read: English teacher and current math student. Ten years later, I'm a former English teacher and former formal math student. It's been a long time since I've regularly done anything approaching real math, and so I'm expecting I'll be posting some questions I should know the answers to, but they'll hopefully be decent questions nonetheless.
