This is going to sound daft, but I'd like to do some maths at home. I got my 'O' level way back in the stone age, but have forgotten a lot of what I learned (and I'm not honestly sure I understood some of it even back then).
What I'd really like to do is to work at home at my own pace, working my way through a school-type text book. When I was at school we did SMP maths - a new book each year, and I was wondering if there's an equivalent set of textbooks now, that I could buy (with the answers at the back so someone can mark my work for me).
Can anyone suggest a book or set of books for me - and if I could get them secondhand - even better.
Thanks!
