No, not at all!
I'll assume you mean the additive inverse, although the following examples can be adapted to the multiplicative inverse as well.
The additive inverse of 5 is -5, and 5 is indeed greater than -5.
However, the additive inverse of -5 is 5, and -5 is SMALLER than 5.
no
It is not clear what you mean by "oppisites" or even opposite. Often a number is the opposite of its opposite. So if the first is greater than the second, the second, which is the opposite of the first, is smaller than the first.
Yes, a prime number is always greater than 1.

No. They are the same.
Sometimes. Also, when depends on what you mean by "opposite": the additive inverse or the multiplicative inverse.

Yes, if the number is less than '1'.Just the opposite, if the number is greater than '1'.

Assuming "opposite" refers to additive inverse, the answer is +65.
Not always, if the smaller number is 0 or a negative number. Then their sum will be equal or less than the greater number.
