👉 In mathematical terms, a "caduciary" is an operator that performs a function on a variable and then returns the result of this operation. For example: ``` f(x) = x^2 x1 = f(caduciary(f(x), 3)) ``` This statement defines a caduciary function `caduciary` which takes another function `f` as input, performs the function on the variable `x`, and then returns the result of that operation.
