Introduction
To understand it you need a basic understanding of ledgers. A ledger consists of a list of transactions.
Each transaction has a credit and a debit book (or account) as well as an amount. This means each transaction affects
one account negatively and one account positively.
To view the balance of a book you simply add up all the credit amounts and deduct all the debit amounts.
