Why do we use the terms ordered and ordered pair?
The pair (2, 3) is the same as the pair (3, 2) but the ORDERED pair (2, 3) is NOT the same as the ORDERED pair (3, 2). In an ordered pair the order of the numbers does matter.
Does the order of numbers matter for set form in algebra?
No, Order does not matter
Does order matter in multiplication?
No. Multiplication is commutative so the order of the multiplicands does not matter. Multiplication is associative so the order in which the operations are carried out does not matter.
Which coordinate in the equatorial coordinate system is like longitude in the geographical coordinate system?
a coordinate system is lines of longuitude and latitude that are used in a map to locate something. There is a coordiante in the Equatorial Coordinate System that is like longitude in the Geographical Coordinate System.....what is the coordinate? Celestial Equator?
What is hierarchy in math?
It is an order which may be implied by definitions or by the number themselves. For example, BIDMAS (or PEMDAS for the US) is a definitional hierarchy. The coordinates of a point is a definitional one: the X coordinate (abscissa) comes first, then the Y coordinate (ordinate). If the space is of three or more dimensions, the Z-coordinate follows and then w, and so on.Numerical hierarchy is simply putting the numbers in order of size.
