👉 Quintuplication is a mathematical operation that involves multiplying four numbers together. It is often used in computer science to represent a function or method that takes four arguments and returns one value. The result of this function can be any value, including zero if all inputs are equal. For example, the function `double(a, b, c, d) -> double` would multiply `a`, `b`, `c`, and `d` together before returning their product as a single result.
