We use curly brackets while writing a set.
- For disjoint sets A and B; $n(A U B) = n(A) + n(B)$ $A \cap B = \varnothing$ $n(A − B) = n(A)$
- No. There is one element inside the brackets. So, it is a singleton set, not a null set.
- Cartesian Product of Set A and B is defined as an ordered pair $(x, y)$ where $x \in A$ and $y \in B$.

Jan 24, 2021 · Suppose set A = {1,3,5} and set B = {5,5,3,3,1,1}. Sets A and B are equal because they contain the exact same elements, namely 1, 3, and 5. Remember, order and multiplicity of elements don’t matter. Let’s look at another example. Determine if the sets A and B are equal.

In sets it does not matter what order the elements are in. Example: {1,2,3,4} is the same set as {3,1,4,2} When we say order in sets we mean the size of the set. Another (better) name for this is cardinality. A finite set has finite order (or cardinality). An infinite set has infinite order (or cardinality).
