摘要:
本文用初等数论的有关性质，建立了弃十一、弃七与弃十三等三种四则运算验算法，它们比通常的弃九法具有一定的优点。）解：∴ｆ１（１３５８）＝５，ｆ１（２９９８）＝６，ｆ１（４０７１２８４）＝８。又∵５×６≡８（ｍｏｄｌｌ）即ｆ１（１３５８）×ｆ１（２９９８）≡ｆ１（４０７１２８４）（ｍｏｄｌ１）∴（）正确。注：上述两例也可用弃七，弃十三法进行验算。４结束语本文所讨论的三种验算法是平行的，其中以弃十一法为最方便。值得说明的是弃十一位比常用的弃九法还只有以下优点。第一，应用法则ｆ１（）得到的最初数值一定比用弃九法得
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
