@BenjaminSteinberg, yes; it seems I misunderstood you. |

@BenjaminSteinberg, or rather, for free monoids / semigroups etc. Some monoids happen to be groups, after all. |

What recent programmes to alter highly-entrenched mathematical terminology have succeeded, and under what conditions do they tend to succeed or fail?
@AndrejBauer, I actually do write that way in private: my notebooks are filled with sentences like "consider a function $f : Y \leftarrow X$ such that..." My only issue with this otherwise wonderful solution is that lambda-abstraction ends up going "on the wrong side." So we end up saying: let $f : Y \leftarrow X$ denote the function $\lambda x(\tau)$ where $\tau$ is a well-formed term of type $Y$. I still think its the best solution, though. |

What are the most misleading alternate definitions in taught mathematics?
Joseph what you're saying sounds interesting. Any idea where I can learn more about the approach that emphasizes closure-operators? |

@MichaelGreinecker, irrespective of its mathematical correctness, the second definition is the right way of motivating the whole thing. We mathematicians need to stop trying to present everything perfect the first-time around. Give the reader a working definition, discuss its problems, and use that to motivate the "proper" definition. That is how you engage the reader. |

Any thoughts as to what factors may have contributed to Bob Soare's success in this venture? |
