What can you understand about Ancient Egyptian numbers compared to modern numbers?

Today my learning intention is to understand place value by using Ancient Egyptian numbers. This week Mr Wong showed his maths group how to use Ancient Egyptian Numbers. But Today I am publishing my work on Ancient Egyptian Numbers. Also I was working by my self so it took a bit longer then expected. I have tried my best and I think I have done well. It is a bit similar to normal numbers, Like The black stick represents one, The Upside down U represents 10 and the spiral represents 100, So I learnt the Ancient Egyptian Numbers Fast.
