We can easily verify that the

ordered pairs generating the congruence [rho] given in Definition 10 are contained in Ker([??]).

Next, define sets [S.sub.c], consisting of

ordered pairs and a singleton defined by:

Thus, inverting each

ordered pair would mean that there is at least one x-value which maps to multiple y-values.

A digraph is strongly connected if, for every

ordered pair of vertices (v,w), there is a directed path from v to w.

For shifting the graph of the function to the right side of the x-axis, some students thought that they should add a constant, and not subtract it from x To clarify this confusion, the teacher encouraged them to analyze the horizontal transformation graphically, write some original and shifted

ordered pairs and think about the transformation as a function that assigned a new value of x, called x', with the same value off(x).

Considering that Sidman's (2000) account holds that equivalence relations consist "of

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

(ii) For every

ordered pair in the connected list of a sensor, the

ordered pair which does not contain the senor itself is identified.

First, it contains every

ordered pair of the form (x, "actual"), for x an individual in the domain of L.

The diameter diam(Cay(G, S)) is the smallest integer d such that for every

ordered pair (g, h) the distance from g to h is at most d.

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.

Kids play games such as Buzz Lightyear Returns From Space to "combine their interest in science with math skills as they complete the Load the Shuttle activity." 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.
