This document discusses debit and credit terminology and transactions. It explains that asset, liability and equity accounts increase on the debit or left side and decrease on the credit or right side. It also notes that in every transaction, the total dollar value of all debits must equal the total dollar value of all credits. Two example transactions are provided: one where the company purchases supplies on credit, increasing both an asset and liability, and one where equipment is purchased with cash, decreasing cash while increasing an asset.
