The less - than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal - length strokes connecting in an acute angle at the left, <, has been found in documents dated as far back as the 1560s. In typical mathematical usage, the less - than sign is typically placed between the two values being compared and signals that the first number is less than the second number. Examples of typical usage include 1⁄2 < 1 and − 2 < 1. Since the development of computer programming languages, the less - than sign and the greater - than sign have been repurposed for a range of uses and operations.
