Well, yes, but Ada isn't maths.  An Ada function can have side effects.
And if it has no side effects, it describes a bunch of steps that
compute a maths function.  It seems wrong to say that an Ada function
that computes the maths factorial function IS that maths function.
The Ada function is a "procedure" or "method" (one of many) for
computing that maths function.
