Tradition aside, we would not still be using this ancient system if it did not work extremely well and efficiently. One could set up a system with pluses and minuses, but it would not be as efficient at generating the data needed for financial statements while making sure that the accounting equation was still in balance. One is more likely to make mistakes in entering data with plus and minus signs, although this is a secondary concern to the issues of uniformity and efficiency. ? Why use debits and credits rather than pluses and minuses? The End
