choose a number system, set of numbers, or set of numerals to research. Look specifically for facts about their history. After you have researched and read multiple (at least 2) sources,write a discussion post with 2 paragraphs totaling 150 words.

- In the first paragraph, summarize and teach us what you learned. Include specific historical facts such as dates, people, and cultures involved.
- In your second paragraph, reflect on what you learned. Tell us what you found interesting and how it may have changed your perspective on numbers. Share any other thoughts you may have after doing your research. References to a minimum of 2 sources are required. List the URLs at the bottom of your discussion post. These don’t count towards the 150-word count.

In your replies, you can comment on what you learned from their post, and compare their information to what you learned. If you have questions or want more information, ask your classmate, and be specific.

Need a hint?
