An element is an item that belongs to a set.
Not sure about maening, but a unit set is a set containing only one element.
If the symbol is like "< " but rounded , then set A < B means every element of set A is found in set B, but there is some element of set B that is not in A. In words it says that A is a proper subset of B.
In set theory, the symbol for a set is typically represented by uppercase letters, such as (A) or (B). The symbol for a subset is denoted by the symbol "⊆", meaning that every element of the subset is also an element of the larger set. If a set is a proper subset (meaning it is not equal to the larger set), the symbol "⊂" is used. Additionally, the symbol "∅" represents the empty set, which is a set that contains no elements.
I believe you are talking about subsets. The empty set (set with no elements) is a subset of any set, including of the empty set. ("If an object is an element of set A, then it is also an element of set B." Since no element is an element of set A, the statement is vacuously true.)

A relation is any set of ordered pairs.A function is a relation in which each first element corresponds to exactly one second element
an empty set does not have any element

Each object in a set is an individual element that is distinct from the others within the set. Sets are collections of unique objects, meaning that each object can only appear once in a set.
element of a set is when two numbers are formed together to form a set and the element is based on a binary question or answer.
No. An empty set is a subset of every set but it is not an element of every set.
The empty element is a subset of any set--the empty set is even a subset of itself. But it is not an element of every set; in particular, the empty set cannot be an element of itself because the empty set has no elements.
A relation is simply a collection of ordered pairs. That is, a relation is a pairing of an element from one set with an element from another set.A function is a special type of relation. In a function, each element from the first set (or domain) is paired with exactly one element from the second set (or range). That is, no domain element is used more than once.I will solve all your math problems. Check my profile for more info.
