  9. Why is $\infty\times 0$ indeterminate? - Mathematics Stack …

    In particular, infinity is the same thing as "1 over 0", so "zero times infinity" is the same thing as "zero over zero", which is an indeterminate form. Your title says something else than "infinity …

  10. Types of infinity - Mathematics Stack Exchange
