Long in the tooth…small on the brain. 
I want to hit my school math again…anything from elementary level on-up. 
I mean to acquire some post-secondary credentials and to pass the math prerequisites i need to brush-up with a wide brush. 
Anything you have, even if it written in, i will take to it with my ‘white-out’ skills. 
I wouldn’t walk 500 miles however i might drive to Gatineau if my tires hold-out a while longer.  😄
