Extra credit: At right (sorry, WWW readers!) is the title page of one of the mathematics textbooks Lincoln may have used in school, Nicolas Pike's Arithmetic. A copy of this text (not Lincoln's own copy, unfortunately) resides in the Heritage Room of the Smiley Public Library, 125 W. Vine St., Redlands, where it is part of the "Books Lincoln Read" collection. Go to the Heritage Room of the Smiley Library (call first to make sure the Heritage Room is open: 7987632) and ask to see Nicolas Pike's Arithmetic from the "Books Lincoln Read" collection (it's not on the shelves). Handle the book very carefully: make sure that your hands are very clean and that you do not crack the spine (do not force the book open all the way if it doesn't want to go!), smudge or tear the pages, etc. Take notes with pencil only (no pens!). I think you'll be surprised to see how much algebra and combinatorics the text contains, despite its title. Pick a favorite topic from the text and write a short report on how Pike's presentation of the topic is similar to and/or differs from how the topic usually is presented today. You may complete this project at any time during the semester.
Next quiz: Really big quiz (some might call it an examination)!

solve this equation? Answer this question by translating alKhwarizmi's work into algebraic equations and labeling the three diagrams he provides. What do we call this technique today?

four corners are missing. Draw a different set of diagrams illustrating the solution technique in which, in the middle diagram, just one corner is missing.
