In Aztec their math is very important because they used their math every day,they used their calendar as we do,important to record like their hearts and arrows.
here's their calendar
Although their math is unique they have a numeration system like we do.
This is how their numeration system looks like.
Thank you,and hope you enjoy my scribe and at the same time i hope you learn something about Aztecs mathematics.

As usual, other people are working on robotics and other people are working on the research. so here it goes....
Babylonian mathematics or Assyro-Babylonian mathematics refers to any mathematics of the peoples of Mesopotamia, from the days of the early Sumerians to the fall of Babylon in 539 BC.
Babylonian mathematical texts are plentiful and well edited. In respect of time they fall in two distinct groups: one from the Old Babylonian period which is 1830-1531 BC, the other mainly Seleucid from the last three or four centuries B.C. In respect of content there is scarcely any difference between the two groups of texts. Thus Babylonian mathematics remained constant, in character and content, for nearly two millennia. In contrast to the scarcity of sources in Egyptian mathematics, our knowledge of Babylonian mathematics is derived from some 400 clay tablets unearthed since the 1850s. Written in Cuneiform script, tablets were inscribed while the clay was moist, and baked hard in an oven or by the heat of the sun. The majority of recovered clay tablets date from 1800 to 1600 BC, and cover topics which include fractions, algebra, quadratic and cubic equations and the Pythagorean theorem. The Babylonian tablet YBC 7289 gives an approximation to accurate to five decimal places.
The Sumerians developed a complex system of metrology from 3000 BC. From 2600 BC, the Sumerians wrote multiplication tables on clay tablets and dealt with geometrical exercises and division problems. The earliest traces of the Babylonian numerals also date back to this period.
The Babylonians made extensive use of pre-calculated tables to assist with arithmetic.
Babylonian mathematicians also developed algebraic methods of solving equations.
I hope you learned something about my research and for the next scribe.. I choose Beatrix.
Thanks for reading!! (:

Here it goes ..
Did you guys know that the word "mathematics" itself derives from the Ancient Greek word "mathema", meaning "subject of instruction". The study of mathematics for its own sake and the use of generalized mathematical theories and proofs is the key difference between Greek mathematics and those of preceding civilization.
Greeks had very clumsy ways of writing down numbers, they didn't like algebra. They found it very hard to write down equations or number problems. Instead, Greeks mathematicians were more focused on geometry, and used geometric methods to solve problems that you might use algebra for.
Greek mathematicians were also very interested in proving that certain mathematical ideas were true. So they spent a lot of time using geometry to prove that things were always true, even though people like the Egyptians and Babylonians already knew that they were true most of the time anyway.
Here are some of the Greek mathematicians :
Greek mathematics constitutes a major period in the history of mathematics, fundamental in respect of geometry and the idea of formal proof. Greek mathematics also contributed importantly to ideas on number theory, mathematical analysis, applied mathematics, and, at times, approached close to integral calculus.
Thats all the information that I've got and Ive learned about my research. Hope you guys learned something too. Sorry for the mistakes. I choose MELANIE DALIGDIG to be the next scribe ;)

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.
