What is an ordered?

Answer 1

Office Order: - issued by competent authority. Office order contains instructions related to office works, change of working hours, instruction on closed holidays, message by senior authorities when they take over some organisation, promotions etc. Office orders are issued periodically like every Monday or on every 1st of month etc. The sequence of the information is pre-decided.

Answer 2

An ordered pair is two numbers in a given order. There is usually some functional relationship between the two, but not necessarily. The x- and y- coordinates of points on the Cartesian plane are an example of an ordered pair - the first number of the pair is the x-coordinate and the second is the y-coordinate.

Examples:

• with y = 2x the ordered pairs (0, 0); (1, 2); (2, 4); (3, 6) are points that lie on the line.
• when measuring the height and foot length of a class there will be a set of ordered pairs (height, foot_length) which gives the height and show size of each individual. These could be plotted on a scatter diagram (with height on the x-axis and foot length on the y-axis), but it is unlikely that there will be a straight line which will pass through all the points.
