Business Accounting Fundamentals

Accounts are the financial records of a firm’s transactions.

Accountants are the professionally qualified people who have the responsibility for keeping accurate accounts and for producing the final accounts.

Final accounts are produced at the end of the financial year and give details of the profit or loss made over the year and the worth of the business.

Methods of Making Payment

1. Cash: The traditional method of payment which is still widely used for small amounts.
2. Cheque: Cheques are not money; they are instructions to a bank to transfer a specified sum in the form of a bank balance to a named person.
3. Credit Card: This allows the consumer to obtain goods and services now but to pay for them in the future.
4. Debit

Chapter 1: The Purpose of Business Activity

Needs vs. Wants

• Need: A good or service essential for living.
• Want: A good or service people would like to have, but is not essential for living. People’s wants are unlimited.

Unlimited wants + Limited Resources = Scarcity (The Economic Problem)

Factors of Production

Factors of production are the resources needed to produce goods or services. All four types are limited in supply:

• Land: All natural resources.
• Labour: The efforts of the workforce used as input into the business.
• Capital: Finance, machinery, and equipment needed for production.
• Enterprise: The skill and risk-taking ability of the person who brings the other factors of production together (e.g., entrepreneurs).

Key Economic Concepts

Qualitative Variables

Nominal Variables

Nominal variables are qualitative variables that cannot be ordered in an ascending or descending manner; that is, they cannot be ranked. For example, blood group.

Ordinal Variables

Ordinal variables are variables that can be ordered in an ascending or descending manner; that is, they can be ranked.

Quantitative Variables

Discrete Variables

Discrete variables are variables whose values are obtained by counting.

Continuous Variables

Continuous variables are variables whose values are obtained by measurement using a scale.

Mean

Adrian Mole's New Year Resolutions

• He will help blind people to cross the road.
• He will hang his trousers up.
• He will put his tapes back in their covers.
• He will not start smoking.

Adrian's Concerns and the Dog's Operation

Why does Adrian think that his spot is growing?
Because he thinks that his mother doesn't know about vitamins.

When the dog has the operation, what does the vet find? Why?
The vet found inside the dog a plastic bag with lots of disgusting things in it. There were even plastic pirates from his father's model ship because the dog had eaten them.

Ideal vs. Practical Voltage Sources

1. Peace of Westphalia (1648)

The Peace of Westphalia established the foundations of the modern international system, including state sovereignty, territorial integrity, and non-interference. African scholars argue that this model was based on European historical experiences and does not fully explain African realities.

2. Realism

Realism is an international relations theory that argues states seek power, security, and survival in an anarchic international system. In Africa, realism helps explain the behavior of regional powers such as Nigeria, South Africa, and Egypt.

3. Liberalism

Liberalism argues that international cooperation, institutions, and economic interdependence can reduce conflict and promote peace. In Africa, it explains the role of... Continue reading "Key Concepts in African International Relations" »

1. Anatomy and Physiology of the Nervous System

The Brain

The brain is the primary organ of the central nervous system (CNS), located within the skull. It regulates body activities, thoughts, memory, emotions, movements, and vital functions.

Parts of the Brain

• Cerebrum: The largest part of the brain, divided into right and left hemispheres. Its outer layer is the cerebral cortex. Functions: Controls voluntary movements, thinking, intelligence, memory, learning, speech, and sensations (pain, touch, temperature).
• Cerebellum: Located below the cerebrum at the back of the brain. Functions: Maintains posture and balance, coordinates muscle movements, and controls fine motor skills.
• Brain Stem: Consists of the midbrain, pons, and medulla oblongata. Functions:
