Additive identity property
We will answers the two questions:1. What is the additive inverse of -72. What's an additive identity.The additive inverse of a number is the number you have to add to the number in order to get 0. (Or more generically speaking, to get the additive identity element of the group or field.) So the additive inverse of -7 is +7. For any real number a, the additive inverse is -a. If z is a complex number, a+bi, then the additive inverse is (-a-bi) since (a+bi)+(-a-bi)=0.The case becomes a little more interesting in fields other than the real or the complex numbers. The integers mod p, where p is a prime, form a finite field. So if we look at integers mod 7, the additive inverse of 5, for example, would be 2 since 5+2=7 which is congruent to 0 in this field.The additive identity in the field of real or complex numbers is 0."Additive identity" means the number you can add to any other number in order to get the same number back. Since -7 + 0 = -7, the additive identity of -7 is 0.In the case of a+bi where i^2=-1, the additive identity is still 0. If it helps you to think of it as 0+0i, that is fine. In the finite field of integers mod p, where p is a prime, we have p as the additive identity. For example, 2 mod 7 is just 2, and if we add 7 it is 9 but that is still 2 mod 7.All of these ideas can be extended to fields of invertible matrices and many other exciting algebraic structures!
Zero is an additive identity element. That means that any number added to zero gives the original number, such as: 3 + o = 0 + 3 = 3, or more generally a + 0 = 0 + a = a
The multiplicative inverse of a non-zero element, x, in a set, is an element, y, from the set such that x*y = y*x equals the multiplicative identity. The latter is usually denoted by 1 or I and the inverse of x is usually denoted by x-1 or 1/x. y need not be different from x. For example, the multiplicative inverse of 1 is 1, that of -1 is -1.The additive inverse of an element, p, in a set, is an element, q, from the set such that p+q = q+p equals the additive identity. The latter is usually denoted by 0 and the additive inverse of p is denoted by -p.
The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
0 is the additive identity for numbers and the identity property is illustrated by 1+0 = 1
The additive identity states that "Any number plus zero is equal to the original number."A + 0 = AHere is an example: 8+0=8 or 25+0=25
The Identity Property, Multiplicative Identity I think it's called... the Additive Identity Property is the number 0... asi: 0+88.
Additive identity property
The additive inverse of a real number is the number that when added to it equals zero, the identity element for addition. That is, the additive inverse of any real number x is -x.

Additive Identity Property: The sum of any number and zero is the original number. For example 5 + 0 = 5.
Zero is an additive identity element. That means that any number added to zero gives the original number, such as: 3 + o = 0 + 3 = 3, or more generally a + 0 = 0 + a = a
800+0=0 is an example of the additive identity property. It says a number + 0 always equals the identical number
an inverse element that can 'undo' the effect of combination with another element. For example if we look at the number 3, -3 is its additive inverse since 3+(-3)=0 and zero is the additive identity element. Similarly 1/3 is the multiplicative inverse since 1/3 x 3=1 and 1 is the multiplicative identity.
The multiplicative inverse of a non-zero element, x, in a set, is an element, y, from the set such that x*y = y*x equals the multiplicative identity. The latter is usually denoted by 1 or I and the inverse of x is usually denoted by x-1 or 1/x. y need not be different from x. For example, the multiplicative inverse of 1 is 1, that of -1 is -1.The additive inverse of an element, p, in a set, is an element, q, from the set such that p+q = q+p equals the additive identity. The latter is usually denoted by 0 and the additive inverse of p is denoted by -p.
Sum, or addition, of numbers has the following properties:Commutative: a + b = b + aAssociative: a + (b + c) = (a + b) + c and so either can be written as a + b + cA set, over which addition is defined will usually (but not necessarily) contain a unique additive identity, which is denoted by 0. This has the property that, for all eelments a, in the set, a + 0 = 0 + a = aThe set may also have additive inverses. An element, a in the set, has the additive inverse, denoted by -a, such that a + (-a) = (-a) + a = 0.Not all sets will have an identity or inverse, for example, the set of counting numbers has neither.
