The "Inequality Sign" is a mathematical symbol used to compare two values or expressions. It indicates whether one value is greater than, less than, or not equal to another. The most common inequality signs are >, <, ≥, and ≤. For example, the expression "5 > 3" means that 5 is greater than 3. Inequality signs are essential in various fields, including algebra, economics, and statistics. They help in solving equations, analyzing data, and understanding relationships between different quantities. By using these signs, we can express conditions and constraints in mathematical problems clearly and concisely.
