Summary of Week 3

The three concepts that form the basis of double-entry accounting are the business entity concept, the accounting equation and the duality concept. The business entity concept means that a business is separate from the owner(s) of the business. The accounting equation for any business states that Assets = Capital + Liabilities. The duality concept means that every transaction has two effects.

The basic principle of double-entry accounting is for every transaction recorded there should be a debit entry and a credit entry in the relevant T-accounts according to the following double-entry rules:
