| For every transaction
that is recorded in a business, there have to be two components
that make up an entrya debit and a credit.
A debit is an increase in an asset item;
a decrease in a claim or expense item.
A credit is an increase in a claim item;
a decrease in an asset or revenue item.

such as a change in assets or a claim on assets.
Assets and Claims on Assets
Debits increase assets or decrease claims on assets (liabilities
and owners' equity). Credits increase claims on assets or decrease
assets. To illustrate, consider the following transaction and journal

equipment which is to be used in the business. To record this
transaction, the owner debits the equipment account because an
asset was increased. The offsetting credit would be to cash.
Generally, debits are listed first
and credits second. The dollar amount of the debit appears on
the left and the dollar amount of the credit appears on the right.
If the piece of equipment illustrated in the transaction above
cost $1000, the journal entry to record the transaction would
