23 kwi 2019 · If you have a definition of "division", then you can ask whether that definition can be applied to zero. For instance, if you define division such that $x\div y$ means "Give the number $z$ such that $y \cdot z =x$", there is no such number in the standard real number system for $y=0$.
The reciprocal function y = 1. As x approaches zero from the right, y tends to positive infinity. As x approaches zero from the left, y tends to negative infinity. In mathematics, division by zero, division where the divisor (denominator) is zero, is a unique and problematic special case.
The number $1$ is that "special" number that satisfies that $1x = x$ for all real numbers $x$. And you see that any (nonzero) number divided is $1$. The question is: what would the equivalent of $1$ be for vectors? With vectors, you don't have such a "unit".
