Inequalities are mathematical statements that show the relationship between two values when they are not equal. They use symbols like < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to) to express these relationships. For example, the inequality 3 < 5 indicates that 3 is less than 5. In everyday life, inequalities can represent various situations, such as comparing heights, ages, or scores. They help us understand how different quantities relate to one another, making them useful in fields like economics, science, and statistics. For instance, income inequality refers to the uneven distribution of wealth among individuals or groups.
