Infinity minus infinity doesn't get me a clear answer.
There is no such thing as ”infinity minus infinity”. You cannot take the limits individually when both terms diverge. You need to look at which terms grows faster.

I thought that his complaint referred to all of the problems associated with "infinity minus infinity".
