Zero.
0 is a whole rational integer in its own right because as for example water freezes at 0 degrees Celsius
x=y is the identity. It is its own inverse. So the inverse is y=x.
They are 0 which is its own additive opposite. 0 does not have a multiplicative opposite.
The inverse of a function is its reflection in the line y=x. so the only function that returns its own inverse is the line y=x or any part of the line y=x
But it IS its own ADDITIVE opposite.
That would be zero. For a number "X" to be its own additive inverse, that would mean: X = -X
0 is its own additive inverse. There is no multiplicative inverse for 0.
No.
One example would be a Galois Field size 4 (ie GF(4)). Here, the elements are {0,1,2,3} and every element is its own additive inverse.
The number that is its own "additive inverse" is zero. (x + 0 = x - 0)For the multiplicative inverse (1/x), the number 1 is its own inverse (also -1). (x times 1 = x/1)x = 1/x is only true where x = 1 or x = (-1)
zero is its own opposite. 0 + -0 = 0
Absolute values are never negative. The opposite, or negative, or additive inverse, of a negative number is the number's absolute value; a non-negative number is its own absolute value. The absolute values of 7 and -5, are, respectively, 7 and 5.
No, it is one of two numbers that has its own multiplicative inverse which is an integer. The other number is -1.
0 is a whole rational integer in its own right because as for example water freezes at 0 degrees Celsius
Assuming the question is about the multiplicative inverse, the answer is, -1. It is its own multiplicative inverse.
x=y is the identity. It is its own inverse. So the inverse is y=x.
They are 0 which is its own additive opposite. 0 does not have a multiplicative opposite.
