"Less" is a comparative term used to indicate a smaller amount or degree of something. It is often used in contrast to "more" to describe a reduction in quantity, quality, or intensity. For example, if a person has less money than another, it means they have a smaller amount of money. In mathematics, "less" is commonly represented by the symbol "<". This symbol is used to compare numbers, showing that one number is smaller than another. For instance, in the expression "3 < 5," it indicates that 3 is less than 5.
