👉 Elementary is a term used in mathematics and computer science to describe the property of an object or process that can be understood by someone with a basic understanding of its structure, properties, and operations. It refers to the ability of an algorithm or program to perform calculations efficiently and accurately on small data sets without significantly slowing down as the size of the input increases. In simple terms, elementary processes are those that can be applied directly to smaller problems or computations without requiring any knowledge beyond basic arithmetic or numerical operations
