In accounting the term dual entry is used often. Other names include Double Entry and Offsetting Entry. It refers to the process of entering an economic transaction as an equation. Remember in math an equation refers to a two sided mathematical statement. Examples include 4= 2 X 2 or more complex equations such as E= MC squared.
Luca Pacioli is considered the father of accounting. A friar living during the 1400’s and a mathematician, he developed the dual entry system of accounting and therefore is credited as the father of modern day accounting.
