if i can find some notes a college teacher helped me "catch" on with, i will make a copy and include with it. Math is fun! but better when a teacher helps th light come on. enjoy bidding!
Also, send address by Sunday night or Monday, so I can ship in Monday mail. May delay slightly trying to find those notes. They were very helpful to me. So I know they would be so to you as well. Shared them with my kids too.
