Keeping track of what you earn, spend, and save are key parts of a _____.

Define each term: A 'personal accounting system' refers to a method or tool individuals use to manage their finances, including tracking income, expenses, and savings. 'Bank reconciliation' is the process of matching bank statements with personal records. A 'balance sheet' is a financial statement showing assets, liabilities, and equity at a specific point in time. A 'trial balance' is a bookkeeping worksheet listing all ledger accounts and their balances to ensure debits equal credits.

Eliminate options that do not fit the context: 'Bank reconciliation,' 'balance sheet,' and 'trial balance' are specific accounting tools or statements, not systems for tracking personal finances comprehensively.
