        Rulers measure cardinal quantities and not ordinal ones. There is no cardinal numbering scheme that starts at 1, all of them “start” at 0. For ordinal numbering schemes, the symbols are arbitrary anyway and you can start with whatever you want. It’s equally valid to start with 1, 0, -1, A, or “aardvark”. The only benefit to picking 1 as the start is to make it easier to count with your fingers while picking 0 lets you easily convert an ordinal quantity to a cardinal one.

        I’ve seen a lot of rulers that actually don’t have a mark at 0 and instead go right to the edge as 0. Typically they are worn down, being made of wood, so the accuracy of the first inch is dubious. To ensure the distance is correct, sliding the ruler down one unit is a good idea. So, my ruler starts at 0 but my measurements start at 1.

            It really depends on what you’re measuring. Good luck measuring the distance from a corner if you can’t get 0 to touch the end.

            Tape measures are almost always designed with this in mind, so you can hook the end over an edge, or butt it up against something and the measurement will be accurate both ways, since the metal end can slide in or out by just the right amount.

        Your job is to move apples from one bin to another. You pick up the first one and set it in the other bin, and say “zero.”?

          There’s another way to think about it which I actually use. Look in the empty bin and say “zero”, then move an apple and say “one”.

    they were never meant to be together, they would confuse the hell out of each other. Imagine they have two kids and she says pick kid[1] from the school, then what?

    Even if the table is correct the instruction needs to be more precise. Is it table header or table body and in which table column?
