DigraphD consists of a finite set V of points (vertex) and a collection of

ordered pairs of distinct points.

In accordance with the definition by Sidman (2000), "the equivalence relation consists of

ordered pairs of all positive elements that participate in the reinforcement contingency" (Sidman 2000, p.

Mathematical concepts that are taught include how to plot data points from a table, how to label

ordered pairs, and how to name coordinates on a grid.

Second, it may contain

ordered pairs of the form (x, "nonactual"), where x is some actually existing individual, set-theoretic or otherwise.

Let us partition the set of odd-sized orbits of [gamma] into

ordered pairs and let ([O.

The notions of tonal "qualia" and "chroma" lie at the heart of the tonal GIS, which Rings represents as

ordered pairs of' scale degrees and pitch classes (sd, pc) respectively.

Written as

ordered pairs (x, y) according to Table 1, the coordinates of the stars are as follows: Atlas (66, 400); Alcyone (204, 468); Merope (224, 793); Maia (249, 336); Taygeta (488, 315); Electra (508, 858); and Celaeno (618, 640).

On Higginbotham's approach, accomplishments are syntactically represented by

ordered pairs of positions for events, and the accomplishment interpretation of a predicate stems from the thematic structures of prepositions and syntactic adjuncts, rather than head verbs.

The interactive games will encourage students to use problem-solving skills to analyze mathematical situations such as visualization and geometric modeling "on the grid using directional words and number of spaces or

ordered pairs of numbers" to solve problems such as the Flight Path Activity.

Although all

ordered pairs situated along the bisector present proportionality between the schemas, these pairs are situated at different distances from the point of maximum interaction.

Often students are taught how to mark

ordered pairs on a plane and produce a graph before they are conceptually ready and have some understanding of how a graph represents "functional" relationships.

The instructional materials used in the first lesson included an overhead transparency that described a relation on a set X as "any set of

ordered pairs in which the first and second components are from X.
