Egyptian Multiplication

Who Were They? They were an ancient civilization that lived about 5,000 years ago in North Africa. They are famous for their monuments as well as their civilization and knowledge.

Egyptians and Math Ancient Egyptians were also great mathematicians.

Egyptians and Math

Egyptians used an interesting method for solving multiplications problems. Their method is called Duplation, which really just means doubling.

How Does it Work? Let’s say for instance they wanted to solve this problem: 7 x

How Does it Work? 7 x 13 Add rows = 13 =

How Does it Work? 12 x 23 = 23 =

How Does it Work? 8 x 23
