Can I use both of setbuilder notations in one article? Boy, this is the best answer I have seen in MO. I have learned a lot from other answers, but I was surprised to read more and more detail in only 7 lines; +2! (I wish). I would add that the two notations look natural enough that the reader will probably not notice if they are both used. |

Great mathematics books by pre-modern authors "Wenn die Zahl a in der Differenz der Zahlen b, c aufgeht, so werden b und c nach a congruent, im andern Falle incongruent genannt. Die Zahl a nennen wir den Modul. Jede der beiden Zahlen b, c heißt im ersteren Falle Rest, im letzteren aber Nichtrest der anderen." Although, as Chandan points out, the original WAS in latin :) |

Great mathematics books by pre-modern authors When I was an undergraduate in Mexico, an important rite of passage was attending the geometry and number theory courses of A. Barajas. He was a legend as one of the founders of Mathematics in Mexico, having worked with Einstein, and organizing the famous 1956 International Symposium on Algebraic Topology. He always started the number theory class by citing the first chapter of Disquisitiones from memory: "Wenn die zahl $a$..." |

Is there a “mathematical” definition of “simplify”? @Ramiro: Entonces es verdad que un radical en el denominador da mas miedo :) Eso explica tambien porque escriben $2\sqrt{2}$ en lugar de $\sqrt{8}$... |
