Lambda Symbols

Lambda symbols (λ) are used primarily in mathematics and computer science to represent a function or a process that can be applied to inputs. Think of them as a shorthand for a specific operation or rule, often defining anonymous functions—functions without names—that you can quickly specify and use. For example, λx.x+1 represents a function that takes an input x and returns x+1. Lambda expressions make it easier to write and reason about functions, especially in programming languages that support functional programming concepts. They help clarify how inputs are transformed into outputs without needing a formally defined named function.
