The term "LessThanOrEqualTo" is a mathematical and programming concept used to compare two values. It checks if one value is either less than or equal to another value. For example, in the expression x ≤ y, it means that x can be either smaller than or the same as y. In programming, "LessThanOrEqualTo" is often represented by the symbol "≤" or the operator "<=". This operator is commonly used in conditional statements to control the flow of a program. For instance, if a variable age is less than or equal to 18, certain actions can be triggered, such as granting access to specific content.
