"The two points of view can be shown to be equivalent" is very hard to believe, without a great deal more detail about just what the "address on the number line" concept means. --Dan << On the subject of what "0.999..." _means_ (which we need to agree on before we can discuss what number it denotes), let me suggest that instead of thinking of it as the sum of an infinite series, one can think of it as an address on the number line. The two points of view can be shown to be equivalent, but pedagogically they're different.
