# are numbers real

That (point at a carton of six eggs) is six. I get it that simple numbers correspond to reality, but that doesn't make numbers real. They got called "Real" because they were not Imaginary. In the end we again end up having conventions based on examples. Sorry if what I am saying don't make sense, it hard to put it into words. So, roughly speaking, I'd say yes, numbers do exist. It only takes a minute to sign up. This is exactly true of our physical world as we know it. upon Dr. James Stein, Professor of Mathematics at CSULB.You can read an article on Isaac Asimov, mathematics and the collapse of empire, inspired by Are Numbers Real? if 'a' is length > 'b' length and 'c' length > 'd' length then product should be +ve But fun! you should read : Interesting post (Needs more structure though). The real numbers can be generalized and extended in several different directions: These truths cannot exist in isolation; they depend on the observer to actualize them. Of course, these days someone could also go their entire lives without seeing a chicken, and they accept that there is an animal which is vaguely involved in the creation of the eggs which they sometimes eat for breakfast. This would be the view of at least one version of mathematical Platonism, and it seems to point to the notion that we are uncovering a deeper and deeper mathematical structure to the universe. now consider every product in expressing as an corresponding area in diagram . We see it all the time, of course. magnitudes But if you're just doing math because you think it's beautiful, then you don't need to care whether it's "real." Should the easiness with which math is applied to the world be a surprise? But, if they are not real, why they are so ... useful, indispensable for the entire umankind ? So, to answer your question, numbers, or triangles, are just as "real" as the application you have found for them. Numbers began as simple representations of everyday things, but mathematics rapidly took on a life of its own, occupying a parallel virtual world. Fiction is "true" when you find that it resonates with your life experiences and goals, and try to live by its teachings. There's no obvious place where we should simply stop. No, I see one image, my 2 eyes function as 1. The Real Numbers had no name before Imaginary Numbers were thought of. operations, may Meaning that they cannot be qualified as … In fact the set {0,1,-1,i,-i} of complex numbers themselves will make problem when we try to give a total order that goes with the usual field operations. The non-negative integers — the "natural numbers" — are just what we call our simplest tools for measuring amount. The introduction of fractional and They are not called "Real" because they show the value of something real. Is it a perceptual construct? But surely the things which we call numbers must exist? Lets say you have 6 chickens & 6 apples before you. The fact that the complex numbers can't even be ordered any more (never mind the quaternions, for which multiplication doesn't even commute) suggests that just because something solves x²+1=0 does not mean that it's a number (that complex numbers aren't 'numbers' in general). So what is a number anyway? But it gets worse. A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. The colour red depends on our sensory apparatus, and the way our brains process the signals sent to us by our eyes. Before reaching this conclusion, Clegg treats readers to an orderly history of math. Mathematicians also play with some special numbers that aren't Real Numbers. only, And these are likely to cause Democrats to heat up the suicide hotline. The angles of any triangle sum to 180 degrees. How do the meanings of *to exist*, *to be*, and *real* differ?
