I understand how to do double entry book keeping, but I am curious on what mathematical principle is Double entry book keeping based off of. I feel like there must be some sort of concept/ proof/ mathematical principle that makes double entry book keeping the most efficient way to do accounting but I can’t seem to find anything on the internet besides how to do Double entry book keeping. Thus my question is what is the name of the law or principle that allows double entry book keeping to successfully keep the accounting equation balanced no matter if one side or both sides of the equation are affected, while only using debiting and crediting to achieve this. Thank you
