The Numbers are RealMary Grayson
Which Numbers are Real? surveys alternative real number systems: systems that generalize and extend the real numbers while staying close to the properties that make the reals central to mathematics. These systems include, for example, multi-dimensional numbers (the complex numbers, the quaternions, ...
Q: Are numbers real? Physicist: This question usually comes in the form of “arecomplex numbersreal?” or “are negative numbers real?” or something along those lines. Turns out you can answer all of these questions at once (if you make up a nice enough definition for what “real” me...
How real are real numbers?, arXiv: math.HO/0411418 - Chaitin () Citation Context ...ervals, when one constructs them legally in NRA. Such a question assumes that it is legal to quantify over intervals of reals, whereas it is illegal to even quantify over real numbers in NRA. Chaitin...

Since x, y, z are all reals located in [0,n], the number of choices for each one is infinite. Without loss of generality, assume that n≥ x≥ y≥ z≥ 0. Then the set of points (x,y,z) is a tetrahedron, or a triangular pyramid. The point (x,y,z) distributes uniformly in...
In the 1970s mathematicians found a simple way to create all numbers, from the infinitely small to infinitely large
If x is a real number, what is the sum of x and the opposite of x? What is the opposite of a real number? Is infinity a real number? What are monomials that are real numbers called? What are the complex numbers? What is the relation between the set of complex numbers, the im...
complex number A number of the form a+bi,where a and b are real numbers and i2= -1 ( or equivalently, i = √-1 ). A complex number is often denoted by a single letter, usually z, we write z=a+bi,where a = Re z(read: "the real part of z") and b= Im z("the ...
