részhalmazkapcsolatok
Részhalmazkapcsolatok refers to the relationships between sets where one set is contained within another. This is a fundamental concept in set theory. The most common relationship is that of a subset. Set A is a subset of Set B if every element in Set A is also an element in Set B. This is denoted by A ⊆ B. If Set A is a subset of Set B, and Set A is not equal to Set B (meaning Set B contains at least one element not found in Set A), then Set A is a proper subset of Set B, denoted by A ⊂ B.
Conversely, if Set B contains all the elements of Set A and potentially more, then Set B
These relationships are crucial for understanding more complex set operations like intersection and union, and they
