Means and ways of arousing and maintaining interest in mathematics teaching can not be :

Question

Accepted Answer

Explanation:

1. **Option 4: To teach calculations** - This is the correct answer because simply teaching calculations does not inherently arouse or maintain interest in mathematics. While calculations are a fundamental part of mathematics, focusing solely on them can make the subject seem mechanical and tedious. Interest in mathematics is better sustained through understanding its broader applications and significance rather than just performing calculations. Teaching calculations is more about skill acquisition rather than engaging students with the subject's richness and relevance.

2. **Option 1: To acquaint with the commercial values of mathematics** - This option is incorrect because understanding the commercial values of mathematics can significantly arouse and maintain interest. When students see how mathematics is applied in real-world commercial contexts, such as in finance, economics, and business, they can appreciate its importance and relevance, which can enhance their interest in learning the subject.

3. **Option 2: To emphasize the practical utility of mathematics** - This option is incorrect because emphasizing the practical utility of mathematics is a powerful way to engage students. When students understand how mathematics is used in everyday life, technology, engineering, and various professions, they are more likely to find the subject interesting and worth learning.

4. **Option 3: To acquaint with the cultural value of mathematics** - This option is incorrect because introducing students to the cultural value of mathematics can greatly enhance their interest. Mathematics has a rich history and has played a crucial role in the development of various cultures and civilizations. By learning about the cultural aspects of mathematics, students can develop a deeper appreciation and interest in the subject.

In summary, while teaching calculations is essential, it does not inherently engage students or maintain their interest in mathematics. In contrast, understanding the commercial, practical, and cultural values of mathematics can make the subject more appealing and relevant to students, thereby sustaining their interest.
