- Mathematicians are very literal minded. "In general" means just what it
- says, i. e. in the general case or instance.
-
- To say that something is not true in general, means that it does not hold
- in each and every case of whatever is under discussion.
-
- "This is in general impossible" means that it's impossible for *at least
- one instance* of the problem. I. e., the problem has no general solution.
