Since a debit in one account offsets a credit in another, the sum of all debits must equal the sum of all credits. There are two different ways to record the effects of debits and credits on accounts in the double-entry system of bookkeeping. Irrespective of the approach used, the effect on the books of accounts remains the same, with two aspects (debit and credit) in each of the transactions.
Debits and Credits
According to historian Jacob Soll in his excellent book The Reckoning, Augustus’ attention to the accounts enabled Rome to flourish. The complexity of Islamic inheritance law served as an impetus behind the development of algebra by medieval Islamic mathematicians. Al-Khwarizmı’s “The Compendious Book on Calculation by Completion and Balancing” devoted a chapter on the solution to the Islamic law of inheritance using linear equations. In the 12th century, Latin translations of al-Khwarizmı’s “Book of Addition and Subtraction According to the Hindu Calculation” on the use of Indian numerals, introduced the decimal positional number system to the Western world. The development of mathematics and accounting was intertwined during the Renaissance. Mathematics was in the midst of a period of significant development in the late 15th century.
The cash account, for example, would reveal the inflows (i.e., additions) and out flows (i.e., reductions) of cash during a particular period of time. Before pacioli’s contribution, some form of double entry system of accounting was already in practice. However, it was pacioli’s book that introduced the system in Europe and other trading countries of the world. As the acknowledgement of his work, Pacioli is known as the “father of accounting” by modern accounting professionals.
Regardless of which accounts and how many are involved by a given transaction, the fundamental accounting equation of assets equal liabilities plus equity will hold. The likelihood of administrative errors increases when a company expands, and its business transactions become increasingly complex. While double-entry bookkeeping does not eliminate all errors, it is effective in limiting errors on balance sheets and other financial statements because it requires debits and credits to balance. In order to achieve the balance mentioned previously, accountants use the concept of debits and credits to record transactions for each account on the company’s balance sheet. Double-entry bookkeeping means that a debit entry in one account must be equal to a credit entry in another account to keep the equation balanced.
The information from the daybooks will be used in the nominal ledger and it is the nominal ledgers that will ensure the integrity of the resulting financial information created from the daybooks (provided that the information recorded in the daybooks is correct). For example, if a business takes out a bank loan for $10,000, recording the transaction would require a debit of $10,000 to an asset account called “Cash”, as well as a credit of $10,000 to a liability account called “Loan Payable”. It was into this politically and religiously charged atmosphere that the innovations in Fibbonaci’s “Liber Abbaci” started merchants and bankers synthesizing alternatives to the abacus and daybooks of unwieldy Roman numerals.
Brief History of Double-Entry Bookkeeping
Another column will contain the name of the nominal ledger account describing what each value is for. For the accounts to remain in balance, a change in one account must be matched with a change in another account. Note that the usage of these terms in accounting is not identical to their everyday usage.
This enabled the Medici Bank to expand beyond traditional banking activities of the time. It started opening branches in different locations, offered investment opportunities, and made it easy to transfer money across Europe using exchange notes that could be bought in one country and redeemed in another. This growth allowed them to dominate the financial world at a time when Florence was the center of the world for trade and education. In Florence, the Medicis were using double-entry accounting to keep track of the many complex transactions moving through accounts. The Medicis’ mathematically-driven financial expertise enabled them to dominate the financial world at a time when Florence was the center of world trade. Indeed, I spent several days in March going through my QuickBook records as I prepared my annual tax filing.
A brief history of double entry accounting
Bookkeeping and accounting are ways of measuring, recording, and communicating a firm’s financial information. A business transaction is an economic event that is recorded for accounting/bookkeeping purposes. In general terms, it is a business interaction between economic entities, such as customers and businesses or vendors and businesses. The first book on double entry system of accounting was written by an Italian mathematician Fra Luca Pacioli and his close friend Leonardo da Vinci.
The Caliphate of Baghdad had provided fertile ground for the advancement of mathematics at a time that Europe was stuck in the quadrivium. Many of the ancient libraries of Rome and Greece had been transferred to Baghdad, where scholars integrated the Hindu numerical notation into geometry and the algebra of linear and quadratic equations. These works were disseminated throughout the Abbasid Caliphate, including into Moorish Spain, making this body of knowledge accessible to Europeans in the colleges at Granada, Cordova, and Seville around the beginning of the twelfth century. The Italian mathematician Fibonacci became exposed to this knowledge traveling extensively throughout Egypt, Syria, Greece, and Sicily. He eventually returned to Italy to publish his “Liber Abbaci” (book of calculation) which promoted the use of Arabic numerals for calculations. The book was written in Latin during the year 1202 and was influential and widely read.

Thanks to the newly invented printing press, his book was mass produced and became a big hit. One of the first readers was Leonardo da Vinci, who at the time was painting The Last Supper. Pacioli’s encyclopedia had a section on the mathematics of perspective painting which fascinated da Vinci. In 1494, he wrote a huge math encyclopedia and included an instructional section on double-entry bookkeeping. Before double-entry, people just kept diaries and counted their money at the end of the day.
Original records (journal and subdivision of journal)
Before the Industrial Revolution, China and India were the wealthiest economies in the World. In China, Qianlong demanded that Britain’s ambassador Lord McCartney kowtow, and informed him that China was in need of nothing from the West. Europe was only a minor economic player in the World at the start of the Industrial Revolution in the late eighteenth century.
Korea borrowed heavily from the Tang, including the innovation of double-entry accounting which was useful in managing the new national Korean bureaucracy. This knowledge was widely disseminated in Asian after Korea began publishing printed books using sand-casted bronze type around 1200 AD. Japan similarly adopted the Tang’s double-entry and other innovations in dress and custom. Al-Khwarizmı’s method was taught throughout the Abbasid empire, in particular in southern Spain. An explosion in the translation and copying of ancient manuscripts from 1200 AD on in Europe included a proliferation of copies of Al-Khwarizmı’s book.
With double-entry accounting, when the good is purchased, it records an increase in inventory and a decrease in assets. When the good is sold, it records a decrease in inventory and an increase in cash (assets). Double-entry accounting provides a holistic view of a company’s transactions and a clearer financial picture.
Under the double-entry system, both the debit and credit accounts will equal each other. The double-entry system of bookkeeping standardizes the accounting process and improves the accuracy of prepared financial statements, allowing for improved detection of errors. For two centuries, during the rise of the great Italian banking centers of Genoa, Florence and Venice, Italian banking recorded transactions, made loans, issued script, and numerous other activities that we would recognize today. Initially, they used single-entry recording (date, and account affected) but this proved error-prone as transaction volume increased. Giovanni di Bicci de’ Medici introduced double-entry bookkeeping for the Medici bank in the 14th century.
In accounting, a debit refers to an entry on the left side of an account ledger, and credit refers to an entry on the right side of an account ledger. Debits do not always equate to increases and credits do not always equate to decreases. Algebra manipulates formulas around an equal sign, the only constraint being the formula on the right of the equal sign must have the same value as the formula on the left. Double-entry bookkeeping manipulates debit and credit balances around an equal sign, the only constraint being the debits must have the same value as the credits. In single-entry accounting, when a business completes a transaction, it records that transaction in only one account. For example, if a business sells a good, the expenses of the good are recorded when it is purchased the good, and the revenue is recorded when the good is sold.
