Abstract:
This article uses the relevant nature of primary theory, and has established three four operational test algorithms, including abandoned eleventh, abandoned seven, and abandoned 13th. They have certain advantages over the usual abandoned nine -way method. ) Solution: 1F1 (1358) = 5, F1 (2998) = 6, F1 (4071284) = 8. ∵ 5 × 6 8 (MODLL) is F1 (1358) × F1 (2998) ≡F1 (4071284) (MODL1) ∴ () correct. Note: The above two cases can also be abandoned, and the thirteenth law can be used for inspection. 4 The three types of test algorithms discussed in this article are parallel, of which the eleven law is the most convenient. It is worth noting that the 11th abandonment is the following advantages. First, the initial value obtained by the application rule F1 () must be much smaller than the original value obtained by the abandonment of the nine methods; second, the number of abandoned nine -method is not verified by the same errors with the same number of numbers with the correct answer to the abacus. The result of the calculation is a two -digit calculation formula. Any errors that cannot be verified by abandoning the nine laws, the application rule F1 () can definitely find the error. The calculation result is a two -digit calculation formula. The abandonment of the nine laws sometimes verify the error. Such as 3254 × l78 = 572912? (The correct result is 579212.), This error is not found with discarding the nine -method verification, and it is wrong to immediately know that the operation result of the case is used to verify the eleven method. references
