(1) On the abacus are: arithmetical arithmetic, omitted (reduced) Kaiping, semi-nine and ninety-nine Kaiping (invented in Japan), the method of false law (double business method, Chinese classical Tianyuan method), correction The method [the classical conjugation method, subtraction Kaiping (subtractive subtraction), in addition to Kaiping (Newton’salgorithm or successive approximation method), do not open equal (table lookup method, joint algorithm, ...). (2) On the computer, there are: successive addition, successive subtraction, trick-adjustment method (Chinese invention), simple and quick Kaiping, table look-up method, joint algorithm, successive approximation method, etc.
