Given two sets A and B, the union of sets A and B (denoted as A ∪ B) is the set of elements belonging to either sets A or B.
N: The natural numbers
A: {1, 2, 3, 4, 5, 6}
B: {3, 4, 5, 6, 7, 8, 9, 10}
A ∪ B: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
N: The natural numbers
A: {1, 2, 3, 4, 5}
B: {6, 7, 8, 9, 10}
A ∪ B: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
N: The natural numbers
A: {4, 5, 6}
B: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
A ∪ B: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Note for this example that A ∪ B = B
