> I have been unpleasantly surprised by how much people struggle to understand this simple concept. Recovered / (recovered+death) is how you do it.

The mistake that you are making in your "simple math equation" is as follows. It is easier to count the number of deaths than it is to count the number of recovered. This messes up your math.

If you miscount a large amount on your recovered numbers, then this will make the death rate look worse than it actually is.
