Calculus Single Variable Hughes-Hallett Gleason, McCallum 4th Edition. There is no highlighting on the pages or tears rips and writing. I don't believe this book has ever been used and old suffers from wear and tear moving around on my personal bookshelves. It is time to pass it along because I know absolutely nothing about calculus and could not even attempt to describe what is on these pages. I have very smart children who could, but not me.
