We will answers the two questions:
1. What is the additive inverse of -7
2. 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!
In mathematics, the additive inverse of a numberais the number that, when addedtoa, yields zero. The additive inverse of 7 is -7.
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.
The number is 7.
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).
The additive inverse of 88 is -88; the additive inverse of -88 is 88. The additive inverse can be though of as the solution of a + x = 0, for any number a.
In mathematics, the additive inverse of a numberais the number that, when addedtoa, yields zero. The additive inverse of 7 is -7.
7. The opposite of 7 is -7, so the opposite of -7 is 7.
-7
7
38/7 x 7/38 = 1 = multiplicative inverse 38/7 + -38/7 = 0 = additive inverse
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.
The question is confusing. The additive inverse of a real number is the same number with the sign changed. For example, the additive inverse of -5 is +5 (or simply 5); the additive inverse of 7 (which is the same as +7) is -7.
No.. if you write 7/2 as -7/2, then that's additive inverse property.
It depends on whether you mean additive inverse or multiplicative inverse.
-5
I assume you mean the additive inverse. The sum of any number and its additive inverse is zero. For example, 7 + (-7) = 0.
It is 7 since 5+7 = 12 which is equivalent to 0 on the clock.
