How do you identify equal sets?

Equal sets are identified when they contain exactly the same elements, regardless of order or repetition.

To determine if two sets are equal, you need to compare their elements. First, list all the elements in each set. Remember, the order in which the elements are listed does not matter, nor does the number of times an element appears. For example, the sets {1, 2, 3} and {3, 2, 1} are equal because they contain the same elements, even though the order is different.

Next, check that every element in the first set is also in the second set, and vice versa. If there is even one element that is in one set but not the other, the sets are not equal. For instance, the sets {1, 2, 3} and {1, 2, 4} are not equal because the element 3 is missing from the second set, and the element 4 is missing from the first set.

It’s also important to note that repetition of elements does not affect the equality of sets. For example, the sets {1, 2, 2, 3} and {1, 2, 3} are still considered equal because they contain the same unique elements: 1, 2, and 3.

In summary, to identify equal sets, ensure that both sets have exactly the same elements, without considering the order or repetition of those elements.
