INVERSE OPERATIONS, and in some instances the order in which these
operations are performed is important in solving EQUATIONs and
evaluating expressions.
See alsoORDER OF OPERATIONS.ordered pairsA pair of numbers written as (x, y),in which the order is
significant. For a GRAPH, the first number corresponds with the point
on the x-axis, and the second number corresponds with the point on
the y-axis. An ordered pair of (3,7) would not graph to the same point
as an ordered pair of (7, 3).
order of operationsThe order for doing math when EVALUATING
EXPRESSIONS, abbreviated as P.E.M.D.A.S.

ordinateOn an (x, y)graph, the xcoordinate is the ABSCISSA, and the y
coordinate is the ordinate. Together, the abscissa and the ordinate
make the coordinates.
origin The INTERSECTIONpoint of the X-AXISand the Y-AXISon a graph,
indicated with O.Its ordered pair is (0, 0).
