Introduction to inequalities

Introduction to Inequalities is a Class 11 Mathematics topic within the chapter Linear Inequalities. It helps students understand how inequalities compare quantities using symbols such as <, >, ≤, and ≥, and how their solutions differ from those of equations. Students learn to represent solution sets on the number line, interpret interval-like ranges, and solve basic linear inequalities. The topic also explains why the inequality sign reverses when both sides are multiplied or divided by a negative number.
