My lack of understanding when it comes to maths is becoming a real problem for me. Can anyone recommend some good A-level books for maths for a GCSE level person who is looking to improve? A-level for the Americans amongst you is 16 - 18 year old level. I would really appreciate some advice as it is a subject I'm not that great with and would love to get a firmer understanding. I'll be looking at maths as related to games programming. So the major areas there are what I am really interested in. Thanks for any help.
