In addition to benefiting students, teachers using history of mathematics may also benefit from its incorporation (Liu, 2003). Teacher who have a good understanding of the history of mathematics are able to creatively pass this on to their students. Understanding the role of history may help teachers understand what they teach and why, thus improving their own teaching practices (pengelley, 2002). Teacher who have an understanding of the progression of mathematics throughout history may use this information to guide them as they lead their students through such progressions (Wilson and chauvot, 2000).
