Explanation:

We record according to the accounting principles:

debit = credit

at least 1 account being debited

and one account being credited

there are no calculation we just post the values of the transactions according to the accounting principles:

assets and expenses : increase from debit  

                                      decreases from credit

liabilities, equity and revenue: increase from credit

                                                  decreases from debit
