I don't even have to explain this because you intuitively understand it, don't you? Would people from all over the world know which floor was the basement level in this elevator?If this elevator existed in America, would someone using it need to speak English so they know that:
B stands for Basement,
LL stands for Lower Level,
L stands for Lobby,
and M stands for Mezzanine?
Have you ever seen a young person struggle to understand the concept of negative numbers? Wouldn't they have an easier time of it if this was their first interaction with -1?
Doesn't it make more sense that the ground floor is zero and then you add one each time you go up?
America, let's adopt this system. It's better.
