Mathematical speed algorithm refers to the calculation method of fast addition, subtraction, multiplication and division by using the special relationship between numbers. Mathematical quick calculation methods can be divided into four categories: Jinhua quick calculation, Wei quick calculation, historical quick calculation and "swallowing gold in the sleeve" created by the ancients. So fast calculation is one of the subjects of computational mathematics, not a separate subject.

Extension:

The operation principle of Jinhua whole brain quick calculation is to stimulate the brain through the activities of both hands, so that the brain can directly produce sensitive conditioned reflex to numbers, so the purpose of quick calculation can be achieved.

(1) With the hand as the operator, an intuitive operation process is generated.

(2) As a memory, the brain can react quickly and express the operation process.
