Help for Mathematics High school I'm looking for mathematics books, courses + exercises for high school level. My daughter was high school certificated but she has stopped her studies for 5 years. She would like to be involved in new educational program but she needs to restore her mathematic capabilities.
Could you help me to identify which mathematics books can help her?
Thanks a lot for your reply,
FR.

A: Playing any mathematical games might be effective, including Sudoku and related games. She might enjoy vihart's videos. You're welcome to introduce your daughter to this site too.
You can't go far wrong with the books of Simon Singh. They'll help get her enthusiastic.
Also, I'd show her some proofs: the best explain why things are true and justify various algorithms.
