Why are (1,2) and(2,1) not equal ordered pair?

It is considered as ordered pair whenever a pair of elements do have a specified order. (1,2) are not the same thing ( 2, 1 ).(1, 2) has 1 in the first slot and 2 in the second. (2,1) are put in the first and second positions of the pair.If a = c and b = d, two ordered pairs (a, b) and (c, d) are equal. A and B are written as (a, b) = ( c , d ).Therefore, The pairs (1, 2) and (2, 1) aren't equal because their elements are not quite the same size.

The pairs ( 1 , 2 ) and ( 2 , 1 ) are not equal because their respective elements are not equal.

Step-by-step explanation:

The pair of elements which are in specific order is called an ordered pair. The pair ( 1 , 2 ) is not same as the pair ( 2 , 1 ). In the pair ( 1 , 2 ) 1 is in the first position and 2 is in the second position. In the pair ( 2 , 1 ), 2 is in the first position and 1 is in the second position.

Two ordered pairs ( a , b ) and (c , d ) are said to be equal if a = c and b = d. We write ( a , b ) = ( c , d ).
