In Objective Mathematics, the concept of integer is often denoted by a symbol, <math>\mathbb{Z}</math>. == Differences == The difference between two quantities A and B, is the quantity which would have to be added to the lesser quantity in order to make it equal to the greater quantity. In the case where there is no difference between A and B, we say that the difference between them is..."

Loosely speaking, standard mathematics defines the square root of, say, 2, to be the positive number <math>r</math> such that <math>r^2 = 2 </math>. It is well known that no rational number satisfies that equation. Solutions to that equation can at..."

In short, this is because an infinite set does not refer to anything that can be perceived. The concept in Objective Mathematics which is closest to that of an infinite set is that of a concept. === But what about extended objects? === There are an unlimited number of points on an extended object. It..."

The practical question to answer, for someone computing this sequence on a computer, is "after how many steps can I stop running the computer program?" The answer is that you should wait until successive steps of the sequence vary by amounts sma..."

Nil is closely related to the standard mathematics concept of an infinitesimal, but it is not the same. Nil is also closely related to the concept of zero. == References == The concept of nil was brought to my attention by Harry Binswanger in his lecture [https://www.youtube.com/watch?v=GwHAObb7tt8 Saving Math from Plato].

A circle should be distinguished from the closely related concept of a loop, or an <math>S^1</math>. To emphasize the distinction from loops, a circle is sometimes called a '''rigid circle'''.

The numerical value of π depends on context: which circle is under consideration, and how precise are one's measurements? == The traditional concept == Standard mathematics says that π is the ratio between the circumference and the diameter of a ''perfect'' circle. Consequently, π is an irrational number." Tag: Visual edit
