this is the definition of sets and elements

Answer 2

ANSWER:

A SET IS A COLLECTION OF OBJECTS . THE OBJECTS ARE CALLED ELEMENTS .

A SET CAN BE DESCRIBED AS A LIST , FOR EXAMPLE D = {5,6,7}

OR WITH WORDS ( OFTEN IN MANY DIFFERENT WAYS )

D = { ALL WHOLE NUMBERS BETWEEN 5 AND 7 INCLUSIVE }

={ ALL INTEGERS BIGGERS THAN 4 AND LESS THAN 8 }

REPETITION IN THE LIST OR CHANGES IN THE ORDER OF PRESENTATION DO NOT CHANGE THE SET . FOR EXAMPLE , THE FOLLOWING LIST DESCRIBE THE SAME SET

{5,5,6,7} = {5,6,7}={6,5,7} .
