Math in China, by Muting
Do you want to know more about the math in ancient china? Let me tell you some, there's a lot a math that the ancient Chinese use, the scales, the abacus and even some of the numbers that the ancient Chinese use. Abacus is one of them, you think the calculator is more easy than an abacus, but when you learn it, it is easy. The abacus have the top and bottom, each circle on top represent 5, and each circle at the bottom represent 1, so at the bottom when you use the thumb move up 1 that means 1, but at the top, when you use the middle finger move down 1, that means 5. That's how the Chinese use the abacus for hundreds ago. The ancient Chinese also use the easy symbol to calculate the math, for example, they place the zero, in to space, so it is easy to remember like the picture that show. They also use the negative numbers, they use it at the last of the number and cross it out so it means negative.
