How many subsets does a set have if the set has one element?
Two. The set {x} has the subsets {} and {x}.
How is the additive identity property different to the additive inverse property?
The additive identity is a unique element of a set which has the property that adding it to any element of the set leaves the value of that element unchanged. The identity is normally denoted by 0. That is: for any X in the set, X + 0 = 0 + X = X Whether or not the set is commutative, addition of the identity always is. The additive inverse of one element of a set is a member of the set (not necessarily different nor unique) such that the sum of the two is the additive identity. The additive inverse of an element X is normally denoted by -X. Thus, X + (-X) = (-X) + X = 0
What is the definition for identity property of multiplication?
The identity property for a set with the operation of multiplication defined on it is that the set contains a unique element, denoted by i, such that for every element x in the set, i * x = x = x * i The set need not consist of numbers, and the multiplication need not be the everyday kind of multiplication. Matrix multiplication is an example.
What do identity property of multiplication mean?
If a set, with multiplication defined over its elements has the identity property it means that there is a unique element in the set, usually denoted by i, such that for every element x in the set, x*i = x = i*x.If the elements of the set are numbers then i = 1.
What is the formula for additive identity?
The additive identity for a set S is a unique element, 0, in the set such that 0 + x = x = x + 0 for all elements x in the set.
What is a relation in which each element of the first set is paired with exactly one element of the second set?
If every element of the first set is paired with exactly one element of the second set, it is called an injective (or one-to-one) function.An example of such a relation is below.Let f(x) and x be the set R (the set of all real numbers)f(x)= x3, clearly this maps every element of the first set, x, to one and only one element of the second set, f(x), even though every element of the second set is not mapped to.
Define identity property?
The identity property of a set, with respect to a binary operation ? is the existence of a unique element in the set, denoted by i, such that for every element x in the set,i ? x = x = x ? i
How many subsets does a set have if the set has one element?
Two. The set {x} has the subsets {} and {x}.

The additive inverse of an element X is normally denoted by -X. Thus, X + (-X) = (-X) + X = 0
Does the 'identity for division' exist?
No, because a field requires the identity element to be commutative. But given an element x, is a set S, there is no single element i such that x/i = x = i/x.
What is a multiplicative identity property?
The property of multiplicative identity, i, of a set S is an element, is that for every element x in S,x * i = x = i * x
What is the definition for identity property of multiplication?

If a set, with multiplication defined over its elements has the identity property it means that there is a unique element in the set, usually denoted by i, such that for every element x in the set, x*i = x = i*x.If the elements of the set are numbers then i = 1.
What is identity of addition?
The identity property for a set states that there exists an element in the set, denoted by 0, such that for all members, x, of the set,x + 0 = 0 + x = x.
What is the formula for additive identity?
The additive identity for a set S is a unique element, 0, in the set such that 0 + x = x = x + 0 for all elements x in the set.
What is identity property of addition?
The identity property for a set states that there exists an element in the set, denoted by 0, such that for all members, x, of the set,x + 0 = 0 + x = x.
What is the definition for identity properties for addition and multiplication?
The identity property for addition is that there exists an element of the set, usually denoted by 0, such that for any element, X, in the set, X + 0 = X = 0 + X Similarly, the multiplicative identity, denoted by 1, is an element such that for any member, Y, of the set, Y * 1 = Y = 1 * Y
