I enjoyed finding out about the history of mathamatics more then I knew before I came to this site on math history. I did find it annoying getting sent to five other sites before I could find some history. I believe this is one of the most frustrating things. I also found the Time Line Graph a bite hard to read but this could be me . On the positive side I did like the Time Line bullet info and will share this with my son. Thanks for the history of math!
