10/17 -- Group A: Egyptian multiplication (Alyssa Perez)

We have learned in the last two weeks that Egyptians worked only with fractions of a very special form. Are there any other mathematical objects or operations that were very different for them as well? We will learn about the Egyptian multiplication and another method, the Russian peasant multiplication, that is related to it. We will see that both rely on binary representation of numbers.
