Professor Fiel on Binary and Hex

If you know what -256 ^ -1 is without using a computer, then you've definitely mastered XOR. The appropriate answer should be dynamic.

Dynamic? Right answer is always 255 (or, uh, 2^8 - 1)

Code:

-1 0000 0000
XOR -          1
=      1111 1111

And yeah Fielz. Enlightening people like this would be awesome, if you did.
