∞·0 is an "indeterminate" expression, meaning that it can have one of many values.
In calculus, you look at how this result was created; looking at how it was created can then lead to a value for that problem. The value might be 0, it might be ∞, or it might be 7 (or any other number).
could Geno or someone else talk me through this some more. Why isn't it 0?
I watched the video Heureka but I don't get how it helps with 0 * infinty ?
