... I trust that everyone can do arithmetic in the rationals. Q is an example of a field. We’ve actually one, Z2 , already. The definition of a field, given as a set of axioms, is on Page 2 of the text. The rationals also have an ordering, using the usual symbol < and its variants. It is easy to define. ...

... the Axiom of Choice to duplicate it. S 2 \ D can be split into two sets, each of which is equidecomposable with S 2 /D. To do this we note that distinct rotations send points of S 2 /D to distinct images. First, let us define an orbit. We will call F x = {f x|f ∈ F } the orbit of such a point x ∈ S ...

Non-standard calculus

In mathematics, non-standard calculus is the modern application of infinitesimals, in the sense of non-standard analysis, to differential and integral calculus. It provides a rigorous justification for some arguments in calculus that were previously considered merely heuristic.Calculations with infinitesimals were widely used before Karl Weierstrass sought to replace them with the (ε, δ)-definition of limit starting in the 1870s. (See history of calculus.) For almost one hundred years thereafter, mathematicians like Richard Courant viewed infinitesimals as being naive and vague or meaningless.Contrary to such views, Abraham Robinson showed in 1960 that infinitesimals are precise, clear, and meaningful, building upon work by Edwin Hewitt and Jerzy Łoś. According to Jerome Keisler, ""Robinson solved a three hundred year old problem by giving a precise treatment of infinitesimals. Robinson's achievement will probably rank as one of the major mathematical advances of the twentieth century.""
