Description: Less than or equal to is one of the methods to illustrate disparities or inequalities in an expression. We don’t get a fixed value for any variable, entity, or expression when we use less than or equal to symbol. It instead specifies the range of values that are less than or equal to a specified item. A number line can also be used to represent these inequalities. Numbers that are less than or greater than are represented by open circles. Closed circles represent numbers less than or equal to and greater than or equal to (≤ or ≥).
