Why is the infinite series of 0 equal to 0, but 0 times infinity is indeterminate? its literally the same answer framed differently giving two opposite answers. anon, why does math hate itself so much?

Because in that operation you are giving the extral detail of how you reach 0 times infinity. You do it by adding 0 multiple each. Each partial sum is 0, so the limit is 0.

There are many other ways to reach 0 times infinity like (1/x)*x^2 but hear the answer is different.

The infinite series of a limit 0 sequence is also indeterminate.

because $\lim_{x\to x_0}f(x) = 0$ and $\lim_{x\to x_0}g(x) = \infty$ doesn't imply $\lim_{x\to x_0} f(x)\cdot g(x) = 0$
