Mathematics

representation on number line

In Class 11 Mathematics, this topic develops a visual understanding of Linear Inequalities through the representation of numbers and solution sets on a number line. Students learn to locate real numbers, mark intervals, distinguish included and excluded endpoints, and interpret symbols such as <, >, ≤, and ≥. The topic also helps them read and communicate inequality solutions clearly, including cases where intervals are combined or restricted.
