Err - we all get a bit cross sometimes, but it's not good for us and it is much better to let it lie and keep your blood pressure down. I see that you get annoyed with people who cannot understand what you refer to as 'basic math'. Well, a lot of highly intelligent people can't. Same way as you probably could not do a mental leap from one literary reference to another. We're all different. In understanding that is the beginning of wisdom (or so I'm told). :)
