Roster form with inequalities

In this Class 11 Mathematics topic from the Sets chapter, students learn how to represent a set in roster form when its elements are defined by inequalities. They practise interpreting conditions such as x < 5 or 2 ≤ x ≤ 6, identifying the appropriate number system, and listing every element clearly within braces. The topic also strengthens understanding of finite sets, endpoints, and the difference between a rule that defines a set and its explicit roster representation.
