Inequality symbols are mathematical symbols used to compare two values or expressions. The most common symbols include greater than (>) and less than (<), which indicate that one value is larger or smaller than the other. There are also greater than or equal to (≥) and less than or equal to (≤) symbols, which show that one value is either larger or smaller, or equal to the other. These symbols help in understanding relationships between numbers and are essential in various fields, including algebra and statistics. They allow for the expression of conditions and constraints in equations, making it easier to solve problems and analyze data.
