    Set theory

    Hi.

    At first, sorry for my english, I´m from Perú.

    I´ve a question:

    It´s a set: a collection of naturals numbers that I can to describe with 14 words in Spanish, or less? (I think in english would be less words, but I dont speak english very good ). Why?


    Thanks

    I don't understand well your question. Are you asking if a collection of natural numbers is a set? If so, then yes because of the definition of a set.
    Anyway, English has much more words than Spanish, so
    (I think in english would be less words, but I dont speak english very good )
    is unlikely to be true.
    Podrías poner tu pregunta en español, así intento traducirla? Porque realmente no entiendo cual es tu pregunta.

    Por ejemplo, "quince" pertenece al conjunto, porque se escribe con menos de 15 palabras.
    Se escribe con una sola palabra : quince. Talvez querrás decir "letras"? De todos modos la respuesta no cambia, es un sí.
    ¿Por qué? Pues mira la definición que da wikipedia de lo que es un conjunto : "
    Un conjunto es una agrupación, clase o colección de objetos denominados elementos del conjunto (aunque cualquier definición dada esconde implícitamente paradojas lógicas o contradicciones).[1] Por objeto entenderemos no sólo entes físicos, como mesas, sillas, etc., sino también entes abstractos, como son números, letras, etc.
    ", acá Conjunto - Wikipedia, la enciclopedia libre.
    For English speakers, the question is
    ¿Es un conjunto la colección de los números naturales que se pueden describir con menos de 15 palabras?
    Is the collection of natural numbers that we can write with less than 15 words a set?
