Zero has no multiplicative opposite (or inverse). However, it has an additive inverse, and that is also zero, since 0 + 0 = 0
The opposite value of a null set would be an infinite set, but infinity is not a real number. The opposite of zero in binary coding is one (on vs. off).

Will the opposite of 0 always sometimes or never be 0?
Sometimes. The opposite of zero depends on the type of function under consideration. For example, the additive opposite of zero is zero. The multiplicative opposite is not defined.
What is the sum of any rational number and its opposite?
If we define "opposite" as the additive inverse, the sum is zero.
What is the sum of any integer and its opposite?
Zero
Why zero is its own opposite?
Because 1, 1 has the opposite of -1 and the in between is zero so there is nothing for zero to be opposite to except 2, itself. If you were to actually look at the shape of 0 on a computer or phone you would notice that it is symmetrical so the opposite to one side is the other. One half is on the negative side of numbers while one half is on the positive.
If you multiply a number by its opposite will make a zero?
No. 3/4x4/3 is 1. 4 divided by 4 is 1; 3 divided by 3 is 3. If it was zero, 3/4x4/3x5=0. It isn't zero, it's five. And, the opposite is called a reciprocal.
