The statement there, "Only one of these explanations is valid" is both unsupported and arguably false:
0 = 0 * 0 0 = 0 * 1 This leads into some fairly deep issues in mathematics. It also has to do with the distinction between relations and functions with function domains with inverse functions, and with concepts of equality. Still, in functional contexts, this is also a real problem and it's entirely reasonable for a programming language or mathematical text to standardize on a single result. That said, this subject easily turns into a heated discussion and is probably better suited for the chat forum than for the programming forum.
