Transaction analysis
• Transaction analysis involves an examination of each business 
transaction with the aim of understanding its effect on the 
accounting equation.
• Accounting equation: 
• A=L+OE
• CA + NCA = CL + NCL + OE
• CA + NCA = CL + NCL + SC + (Op. RP + R – E – D)
Transaction analysis
Examples:
1. Borrowed $10 000 cash from the bank.
2. Purchase equipment for $50 000 cash.
3. Catering services provided for an office function; billed customer for $1000
Assets = Liabilities + Owner’s Equity

Double entry accounting
• The Golden Rule: The accounting equation must always balance.
• It means Debits (Dr) = Credits (Cr).
A + E = L + OE* + R
↑ Dr Dr Cr Cr Cr
↓ Cr Cr Dr Dr Dr
* To help you memorise how debits and credits work, here OE = SC + Op.RP – D 
(i.e., R and E are expanded in the accounting equation).
Journal entries
• Journal entries are a shorthand version on transaction analysis.
• They are prepared using the rules of debit and credit : Dr = Cr
Examples:
• Machinery with a life of 5 years is purchased for $5 000 cash:
Dr Machinery  5 000
Cr Cash  5 000

DQ3.3 – R&OE
Why does an increase in expenses result in a decrease in shareholders’
equity? What other part of the accounting equation is likely to be affected?
Expenses decrease profit, and profit increases retained profits, 
which is a part of shareholders’ equity. 
It is likely to also increase a liability, such as a payable or decrease 
an asset such as cash.

normally have a credit balance?

Why does an increase in revenues result in an increase in shareholders’
equity? What other part of the accounting equation is likely to be affected?
Revenues increase profit, and profit increases retained profits, 
which is a part of shareholders’ equity. 
It is likely that revenues (sales) also increase an asset, such as cash, 
or accounts receivable.
