So, I lost my maths book and since it's close to exam time, our teacher says it may have been stolen. :|

And now, I borrowed my friends maths book and I have to copy out THE WHOLE MATHS BOOK into a new book.

I'm having trouble with:

Converting decimals into fractions

Set builder and interval notation (inequalities)

Perimeter and area of compound shapes

Volume for shapes (cylinder is hard)

Factorising

Please help?

Thanks!
