In programming languages we are habitual of using asterisk (*) symbol for multiplication sign. I was wondering how time can map to a cross (or x alphabet symbol) symbol. Then I went back to my primary class education which taught me 3 times 2 is equal to 6 (3x2=6).

Small x alphabet is actual multiplication sign in mathematics. Formal proof for $ (-1) \times (-1) = 1$ - Mathematics Stack Exchange. Is there a formal proof for $(-1) \\times (-1) = 1$? It's a fundamental formula not only in arithmetic but also in the whole of math.

Is there a proof for it or is it just assumed? Why is $\infty\times 0$ indeterminate? - Mathematics Stack Exchange. Your title says something else than "infinity times zero". Additionally, it says "infinity to the zeroth power".

It is also an indefinite form because $$\infty^0 = \exp (0\log \infty) $$ but $\log\infty=\infty$, so the argument of the exponential is the indeterminate form "zero times infinity" discussed at the beginning.
