TRANSPOSITION ERROR
When two adjacent numbers are transposed, the resulting mathematical error will always be divisible by 9 (e.g. (72-27)/9 = 5). Bank tellers can use this rule to quickly find their errors in many cases. Transposition errors also occur in accounting firms, brokerages and all other areas of finance.
