Someone recently asked me why a negative $\times$ a negative is positive, and why a negative $\times$ a positive is negative, etc. I went ahead and gave them a proof by contradiction like this: As...
Your title says something else than "infinity times zero". 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.
I'd even start with 0.5 times 3.5 -- it feels normal to add 0.5 to itself 3 times, then not-too-bad to add it once more 1/2 a time. That establishes "add 1/2 a time" is fine and fits the repeated-addition pattern.

"Infinity times zero" or "zero times infinity" is a "battle of two giants". Zero is so small that it makes everyone vanish, but infinite is so huge that it makes everyone infinite after multiplication. 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 ...
I usually use geometric block to do multiplication. $4\times 5$ is the number of $1\times 1$ blocks inside a rectangle with sides $4$ and $5$ that is $20$ $1\times 1$ blocks. in the case of $0.5\times 0.5$ we have a square with side $0.5$ and we want to know the number of $1\times 1$ blocks inside that.
Simon also points out that according to this benchmark, it appears that it's faster in Safari and Chrome (but not Firefox) to repeat a character multiple times by simply appending using a for loop (although a bit less concise).

Bonus 2: repeating a 2D array this way takes a little bit more work, converting to rows a few times before wrapping back to the desired dimensions. You can of course use LET to keep things tidy if you don't want to define the array twice:
