Ethics

My theory of ethics was Rule Utilitarianism, it is similar to Utilitarianism, which is a theory of ethics which says that we should do the things that promote the most general happiness. Rule Utilitarianism is similar but it says we should follow rule that promote general happiness instead of doing what we think will promote general happiness.
According to this theory of ethics, my Math Addict classes are ethical, as I am helping people, and I am doing so in a way that is not very bothersome. This brings up the happiness of my peers as they are getting better at a subject and it is bringing up the happiness of the teachers as they can move on with the lessons.
