In the set of rational numbers what is the identity element for multiplication?
1 is the identity for multiplication. 1*x = x = x*1 for all rational x.
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.
0 and 1 are not prime numbers but apparently they have their own special names what are they?
They both considered "identity elements". 0 is actually the identity element under addition for the real numbers, since if a is any real number, a + 0 = 0 + a = a. Mathematicians refers to 0 as the additive identity (or better said, the reflexive identity of addition). 1 is a separate and special entity called 'Unity' or 'Identity element'. 1 is actually the identity element under multiplication for the real numbers, since a x 1 = 1 x a = a. Mathematicians refers to 1 as the multiplicative identity (or better said, the reflex identity of multiplication).
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 is multiplying a number by 1 that gives a product identical to the given number?
That is because 1 is the identity element of numbers with respect to multiplication.
What is the inverse property of multiplication?
subtractionthe answer of this question is division NOT SUBTRACTION!!!!!!!!!!!!!!!!!* * * * *No, it is not division either - that is the inverse function to multiplication - which is a different thing.An element y, of a set is said to be the inverse of the element x in the set if x*y = y*x = i where i is the multiplicative identity for the set. y is denoted by x-1In ordinary multiplication of numbers, i = 1.
In the set of rational numbers what is the identity element for multiplication?
1 is the identity for multiplication. 1*x = x = x*1 for all rational x.
Why is zero not an identity element in subtraction?
If you subtract zero, you get the original number back.The reason it is not usually considered the "identity element of subtraction" is that the base operations are addition and multiplication - subtraction and division are simply the inverse operations to addition, and multiplication, respectively. When defining numbers in an axiomatic system, the emphasis is on those base operations.

Why there is a need of a null vector?
It has the role of the identity element - same as, in the case of real numbers, the zero for addition, and the one for multiplication.
What is the identity property of multiplication and addition?
The identity property of multiplication asserts the existence of an element, denoted by 1, such that for every element x in a set (of integers, rationals, reals or complex numbers), 1*x = x*1 = x The identity property of addition asserts the existence of an element, denoted by 0, such that for every element y in a set (of integers, rationals, reals or complex numbers), 0+y = y+0 = y
Does division and multiplication involve negatives?
Not by necessity, but multiplication and division aredefined for negative numbers.
What is the definition for identity property of multiplication?

That is because 1 is the identity element of numbers with respect to multiplication.
What are the identity elements for the addition and multiplication of rational numbers?
For addition, 0 and for multiplication, 1.
If 1 isn't a prime or composite number then what is it?
It is the identity element of multiplication. That puts it in a special category.
