There is a philosophical question: "If you imagine a world without numbers, how will it be seen?" Can somebody answer this question?! Last edited by skipjack; December 28th, 2017 at 06:36 AM.

In your descriptive sentence you've already postulated the existence of numbers. You say "a world", i.e. one world. Thus implying the existence of the number 1. The fact that you had to discriminate "one" world implies that there can be more than one world, thus implying the existence of the numbers greater than 1. Some things are so fundamental you can't just imagine them away.

My first thought is only positive mathematics without the existence of negative numbers Get it>? who uses subtractive mathematics? hence numbers started not to exist

There's a tribe that doesn't use numbers. "Curiously, although not unprecedentedly, the language has no cardinal or ordinal numbers. Some researchers, such as Prof. Peter Gordon of Columbia University, claim that the Pirahã are incapable of learning numeracy. His colleague, Prof. Daniel L. Everett, on the other hand, argues that the Pirahã are cognitively capable of counting; they simply choose not to do so. " https://en.wikipedia.org/wiki/Pirah%C3%A3 "Equally perplexing: In their everyday lives, the Pirahãs appear to have no need for numbers. During the time he spent with them, Everett never once heard words like "all," "every," and "more" from the Pirahãs. There is one word, "hói," which does come close to the numeral 1. But it can also mean "small" or describe a relatively small amount  like two small fish as opposed to one big fish, for example. And they don't even appear to count without language, on their fingers for example, in order to determine how many pieces of meat they have to grill for the villagers, how many days of meat they have left from the anteaters they've hunted or how much they demand from Brazilian traders for their six baskets of Brazil nuts." http://www.spiegel.de/international/...a414291.html Last edited by Maschke; December 28th, 2017 at 10:59 AM.
