Ta da!
Isn't it more that *numbers* are constant -- 2 apples will always be 2 apples and not twice as many, not ever -- but that the *symbols* used to describe them are arbitrary? The 2, the 4, the i?
Well, define 2. Not the symbol, but the concept it's signifying. There's nothing physical you can point to and say, "That's a 2." You can do math as just a symbolic way of describing the physical world -- 2 is the concept of one object plus another of the same object -- but that gets pretty limited pretty quickly. There gets to be a point where you're using the numbers to represent pure concepts that can't be represented physically.
It's all here, in the link above the posting box.
Thanks, ita. Somehow I missed that quick edit.
Since I am going to do my first webpage, this is all extremely useful info. Thanks.

Can't you do that with sufficient repetitions of two objects? Sufficient to distance it from the object itself, and instead focus on the quantity? It's not even that 2 is the concept of one object plus another of the same object, unless you spend a fair amount of time defining "same" and "object" which seem to be much harder than 2.
Yesterday morning before work it was -15 F here, with -30 F windchill. It had gotten down to -18 F overnight, apparently.
Today it rose to a balmy 4 above.
I went for a walk.
I also noticed fresh bicycle tire tracks in the snow.
WTF?

None of the quickedits work in most of the real world (we stole the WebCrossing ones and expanded a little). You'll need to use my intermediate steps in my wordy post.
problems in engineering and physics where,
Electronics uses imaginary numbers to explain the relationship of pure resistance, capacitance and inductance in a circuit in what's known as rectangular notation. Resistance is described with real numbers and capacitance and inductance are described with imaginary numbers. That is because of the electrical relationship between the three. They don't physically correspond. When one element of the circuit is doing one thing, the others are doing something a little different. So, in order to describe where one element is in relationship to another along an X/Y graph, we use imaginary numbers. In all, it allows us to model the behavior of a circuit and what will happen to it if we change one of the elements. So, while it may be hard to understand, it is what allows us to develop all kinds of electronics equipment. 'Tis a necessary evil.
