Babylonian multiplication

This applet allows you to explore one of the algorithms used in ancient Babylon to perform multiplication.
  • Take a look at the MacTutor page on Babylonian mathematics.
  • Which algorithm is illustrated in the applet? (Hint: the product illustrated is 2 x 5.)
  • Visualize other products by moving the pink point, and then the mauve one.
  • Write a short note connecting the applet to the algorithm.
  • How might you use this applet in the classroom, integrating history & maths?
