> Solving the second implies in some way having already solved the first, due to the nature of positional systems. Untrue. (Edit: actually true). It works perfectly well to have a decimal number system using digits 1-10 instead of 0-9. For sake of notation, let's say A is the digit representing 10. "A" = 10, "11" = 11, "19" = 19, "1A" = 20, "21" = 21, etc. Edit: actually, I misread your argument. What you argued is definitionally true.
