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.
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.

The class, if you don't already know is divided into two groups. One group is learning how to build robotics and the other group is doing research to try and find out about math in there ancient civilization.
The group that I am in is the one where we do research, the civilization I have chosen to do my research on is the Indians.
Now I will tell you some facts about Indian Mathematics.
- Indian Mathematics emerged in South Asia from Ancient times until the end of the 18th Century
- During the Classical Period of Indian Mathematics, which was 400 AD to 1200 AD important contributions were mad by Aryabhata, Brahmagupta and Bhaskara the second.

1. Choose a civilization from early times like: Greeks, Romans, Babylonians, Egyptians, Chinese, Mayans, Indians, Sumerians,Aztecs, ...
2. Create notes that will answer the folowing questions:
a. where or when was the math originally invented?
b. how did te civilization know their math was important?
c. what was the purpose of the math?
d. how were the numbers developed? What did they look like?
e. did they use any operations in their math?
f. did the math spread? Do we use it today?
g. which segment of the civilization used the numbers/math?
h. did theyhave laws of math? what might they have been?
i. what is the first evidence of math in the civilization?
j. if the civilization had not invented or used math, how would it have affected our civilization?
3. You will need to create a power point presentation that will include the following items:
A map of the area that the civilization flourished, a picture or diagram of any of the numbers that the civilization used, any other relevant pictures that you can think of, answer the questions above and any other questions you came across,be able to present your findings to the class.
