The document discusses the importance of understanding the purpose and reason for studying a subject like accountancy. It uses examples of a student's academic year and a businessman's business transactions to illustrate how language barriers could cause issues. Without knowing the language or accounting, a student couldn't take notes, learn topics, or get graded. Similarly, a businessman wouldn't be able to record transactions or know the year's profits. The document emphasizes that accountancy provides the language for recording and understanding business transactions, which is why it is important to study.
