Which was invented first: the wheel or the concept of the number zero?

Note:

The number zero would still be the number zero even if people throughout the world used a symbol such as "Z" to represent it rather than a symbol that -- depending on the font -- looks a bit like a wheel.

Consider five. The Roman "V" was fine and couldn't be used in a positional number system simply because VI (six) would be confused with fifty-one. In other words, the individual symbols for Roman numerals are conventionally used only to represent numbers via the additive system.

The individual symbols are the clue as to what system is being used, except that, for example, 1011 might mean eleven if binary is being used.
