Count With Your Fingers - Chinese Style!

• 

Who would have thought it was possible to count up to one hundred thousand, just on one hand?
The Ancient Chinese did!
In this system, each successive finger represents an increase of one in the power of ten, allowing numbers up to ten to the power of five!
When both hands were used, the Chinese could add, subtract, multiply and divide, only using their fingers!
Now that's clever!
