That is the dividend. Place it under the division bracket. The dividend is divided by some other number; that is the divisor, and it goes to the left of the bracket. Perform the division.increment: An increment is a small, unspecified, nonzero change in the value of a quantity. The symbol most commonly used is the uppercase Greek letter delta ( ). The concept is applied extensively in mathematical analysis and calculus.

The doublestruck capital letter Q, Q, denotes the field of rationals. It derives from the German word Quotient, which can be translated as "ratio." The symbol Q first appeared in Bourbaki's Algèbre (reprinted as Bourbaki 1998, p. 671).

In LaTeX it is coded as \cong. ∼ ∼ is a similarity in geometry and can be used to show that two things are asymptotically equal (they become more equal as you increase a variable like n n ). This is a weaker statement than the other two. In LaTeX it is coded as \sim. ≃ ≃ is more of a grab-bag of meaning.

A relation helps to establish a connection between the elements of two sets such that the input and output form an ordered pair (input, output). A function is a subset of a relation that determines the output given a specific input. All functions are relations but all relations are not functions.
