Hello, Charley!
Web2.0Calc is a site dedicated to helping people understand and appreciate all forms of mathematics. The forums are a place for people to ask questions about parts of math they don't understand, whether it's a specific question or a short explanation of a whole part of math. If you have any other questions, feel free to ask!
Happy to welcome you to the family,
