Why is zero multiplied by infinity not defined as zero?
gpt
Infinity isn't a number (you can't point to it on a number line), and since both things that you're multiplying have to be actual numbers, you can't multiply anything by infinity.  In general, infinity is not a valid term to use in any "normal" math.

What you *can* do is take the **limit** of "0 * x" as x approaches infinity, and the solution to that limit is zero.
