prove of sign bit extension?

can somebody help me to prove in mathematical approach why the sign bit extension does not change the numerical value of 2′s complement number??
thx in advanced

I should say I don’t exactly understand your question.

If you change the sign bit of 0xFFFF it becomes 0x7FFF. Hence the numerical value has changed from -1 to 32767( assuming short int of 2 byte size)

Is this what you ask? If so, then No! it does change the value

2′s Complement:
The 2′s Complement is used only for computers to store data. If the size of an int is 4 bytes. The first bit is used as sign bit. So if it is one the number is negative. If else it is positive.

Reason for 2′s Complement:
1′s complement will just convert the 0′s into 1′s and 1′s into 0′s. So a number -1 will have 0xFFFE as its 1′s comp representation. Its just fine the only problem is 0 has 2 values in this representation 0xFFFF and 0×0000. 2′s complement evolved just to resolve this problem by adding an extra 1 to the negative numbers.

Sign bit’s usage:
So the sign bit decides weather the number is positive or negative and hence choose the algorithm to use( Add 1 or not ).
