  • Proof of $0x=0$ - Mathematics Stack Exchange
    Since $0$ is the neutral element for the addition, we have that $$0x = (0 + 0)x$$ and because of distributivity we find that $$ (0 + 0)x = 0x + 0x $$ Hence we find that $$0x = 0x + 0x$$ so $0x$ also acts as the neutral element Because of unicity of this element, we have that $0x = 0$ $\textbf {Edit:}$ As Will Jagy commented, you could also use that $0x$ has an additive inverse, denoted by
  • c++ - What does \0 mean? - Stack Overflow

  • Limit of $x \\log x$ as $x$ tends to $0^+$ - Mathematics Stack Exchange
    as $x\log x<0$ for small $x>0$, and then using the substitutions $x\mapsto \frac {1} {x}$, $x\mapsto x^2$ The squeeze theorem then implies that the limit indeed is 0
