Egyptian Mathematics Scribe Post

Oct.28, 2009

Hey Guys! For today, I am going to write about, what I've learned while researching Egyptian Mathematics. So, Here it goes.

I learned, that the Egyptian civilization were the first civilization to use the scientific arts. Although, they've had a lot of achievements, there are no proofs of how they reached their mathematical conclusions. Their decimal system contains 7 different symbols:
  • 1 is shown by a single stroke
  • 10 is shown by a drawing of a hobble for cattle
  • 100 is presented by a coil of rope
  • 1,000 is a drawing of a lotus plant
  • 10,000 is presented by a finger
  • 100,000 is presented by a tadpole or frog
  • 1,000,000 is a figure of a god with arms raised above his head

Egyptians performed multiplying and dividing, by doubling and also halving. They introduced the earliest fully developed base 10 numeration system. The Egyptians used the Akhmim Wooden Tablet (AWT), which lists 5 divisions of a unit called a hekat. Two number systems were used in Ancient Egypt. One was written in hieroglyphs. The second number system was written as a digital system. It was a one-number-to-one-symbol system, and it was completely different from the hieroglyphic system.

Egyptian multiplication was done by repeated doubling of the number. The number 1, would have the multiplicand written next to it. Then, it was added to itself, and the number 2 would have the result written next to it. They would continue the process until the doublings gave a number greater than half of the multiplier. Then, they would repeatedly subtract the doubled numbers from the multiplier, to select which of the results of the existing calculations should be added together to create the answer.

For example:

As you can all see, Egyptian Mathematics is way different than the kind of math we use today. Well, that's all I have for u guys. I hope, that all of you have learned something from my post.
