About:
Retired math, physics and chemistry teacher. I have a private tutoring business via Skype during school months. Happy to help for free during the summer - it keeps me in tune.
I don't like to simply supply an answer; I'm more likely to respond if the questioner has showed some effort in trying to arrive at the answer. What have you tried? Have you drawn a picture? Did you Google the concept?
