The speed algorithm is
Quick calculation is one of the mathematical calculation methods. Fast calculation refers to the fast operation of addition, subtraction, multiplication and division by using the special relationship between numbers, and the fast calculation method of adding, subtracting, multiplying and dividing any number quickly and accurately with one thought and one method. This operation method is called speed algorithm and heartbeat algorithm. The quick calculation methods include whole brain quick calculation and Wei's quick addition, subtraction, multiplication and division by using the special relationship between numbers.
Concept, a mathematical calculation method, enables learners to quickly and accurately master the fast calculation method of addition, subtraction, multiplication and division of any number in a short time with an idea and a method without any calculation tools. So as to quickly improve learners' quick calculation ability in oral and mental arithmetic.
