Calling all maths students and teachers: "You have just used your last sheet of graph paper, and you've got plenty more work to do. When the bookstore has run out, or it's 2 o'clock in the morning, how do you finish your homework?"
The answer may be to visit the website of Mathematics Help Central where you can download graph paper to your computer and print as many copies as necessary - free.
The website has been set up by an American maths student, Holly Camp, who went back to college after separating from her husband and being left with two young children to bring up. It also includes homework help and lecture notes.
