Also known as linear mapping, linear transformation, linear function, linear homomorphism, linear mapped
mapping that preserves the operations of addition and scalar multiplication
A linear map is a type of mathematical function that preserves two basic operations: when you add inputs together, the output is the same as adding the outputs separately, and when you multiply an input by a number, the output gets multiplied by that same number. Linear maps matter because they're fundamental tools in mathematics and science for describing relationships between quantities that scale and combine in predictable, proportional ways.
