试算结果不平衡,一般有除二法(即反方法)和除九法(即移位或倒置法)两种检查方法,这里只着重谈谈除九法。除九法是将不平之数(差数)用九除,如果能够除尽,而且所得的商数与帐簿记录有相同的数字,这可能是因为移位引起的错误。如将100误为10(往后移),由于这种错误使原数缩小了九倍,如将10误为100(往前移),则使原数扩大了九倍。因此将不平数以九除之,会得其原数,这就便于查找。但有的差错是由于倒置(即颠倒)造成的,其差数(即不平之数)同样可以被九除尽,如用移位的方法去查找是得不到效果的。倒置即颠 Trial results are not balanced, there are generally two methods (that is, the anti-method) and the addition of nine (ie, displacement or inversion method) two checks, here only focuses on the addition of nine. Dividing the nine numbers by dividing the number of irregularities by nine means that if the numbers are divisible and the resulting quotations have the same numbers as the books, it is probably because of the error caused by the shift. If you mistaken for 100 100 (move backward), due to such a mistake to reduce the original number nine times, such as the 10 mistaken for 100 (forward), then the original number expanded ninefold. Therefore, the number of uneven addition to nine, will get the original number, which is easy to find. However, some mistakes are due to inversion (ie, reversed) caused by the difference (ie, uneven number) can also be divided by nine, such as using the shift method to find no effect.
