👉 Threaded math, also known as nested or recursive mathematical expressions, involves defining a function or operation that calls itself within its own definition. This allows for the creation of complex, layered expressions where each level can manipulate or transform the result of the previous one. For example, a simple function might take another function as an argument, apply it to some input, and then return the result of that operation. This technique is fundamental in areas like functional programming, where it enables the creation of higher-order functions, recursive algorithms, and data transformations. Threaded math can elegantly handle problems that require repetitive or hierarchical operations, making it a powerful tool for modeling real-world processes with multiple stages or dependencies.
