  2. Face value - Wikipedia

    en.wikipedia.org/wiki/Face_value

    Face value can be used to refer to the apparent value of something other than a financial instrument, such as a concept or plan. In this context, "face value" refers to the apparent merits of the idea, before the concept or plan has been tested. Face value also refers to the price printed on a ticket to a sporting event, concert, or other event ...

  3. Notional amount - Wikipedia

    en.wikipedia.org/wiki/Notional_amount

    In simple terms, the notional principal amount is essentially how much of an asset or bonds a person owns. For example, if a premium bond were bought for £1, then the notional principal amount would be the face value amount of the premium bond that £1 was able to purchase. Hence, the notional principal amount is the quantity of the assets and ...

    For example, saying "the absolute value is denoted by | · |" is perhaps clearer than saying that it is denoted as | |. ± (plus–minus sign) 1. Denotes either a plus sign or a minus sign. 2. Denotes the range of values that a measured quantity may have; for example, 10 ± 2 denotes an unknown value that lies between 8 and 12.

    When said of the value of a variable assuming values from the non-negative extended reals {}, the meaning is usually "not infinite". For example, if the variance of a random variable is said to be finite, this implies it is a non-negative real number, possibly zero. In some contexts though, for example in "a small but finite amplitude", zero ...

  6. Face (geometry) - Wikipedia

    en.wikipedia.org/wiki/Face_(geometry)

    In elementary geometry, a face is a polygon [note 1] on the boundary of a polyhedron. [3] [4] Other names for a polygonal face include polyhedron side and Euclidean plane tile. For example, any of the six squares that bound a cube is a face of the cube. Sometimes "face" is also used to refer to the 2-dimensional features of a 4-polytope.

    For example, the constant π may be defined as the ratio of the length of a circle's circumference to its diameter. The following list includes a decimal expansion and set containing each number, ordered by year of discovery. The column headings may be clicked to sort the table alphabetically, by decimal value, or by set.

    def – define or definition. deg – degree of a polynomial, or other recursively-defined objects such as well-formed formulas. (Also written as ∂.) del – del, a differential operator. (Also written as.) det – determinant of a matrix or linear transformation. DFT – discrete Fourier transform.

    To give a numerical example, a 3% UK government war loan will trade at 50 pence per pound in a yield environment of 6%, while at 3% yield it is trading at par. That is, if the face value of the loan is £100 and the annual payment £3, the value of the loan is £50 when market interest rates are 6%, and £100 when they are 3%.
