The question isn't too clear, but I'll assume it means, "what is a negative number minus a positive number?" The answer to that is: a negative number. To explain why, imagine the number line. A negative number is to the left of 0. Subtraction says to go reverse the direction you would if you were adding the number. Adding a positive number would mean you're going to the right. So you just go farther to the left. Wherever you are, you're still on the left side of the 0, so the result is a negative number.
If the byte represents a signed number, values commonly go from minus 128 to plus 127. If the byte represents an unsigned number, values commonly go from 0 to 255.
There is no last number, if that's what you mean. Whatever number you choose, you can always add one more, to get an even larger number.
-6-8=-14 if it would be +, you would go forward, but as it's -, you go backward.
