You might be right, I am still learning this new stuff and I have a way of making it more confusing than it needs to be, I guess.

If it is -2147483647 then the hex would be $FF8000001 ??? Now I see why you asked about the carry.
Or if -2147483647 +1 = -2147483646 = $FF80000002 and the absolute value would be $7FFFFFFE

I will be quiet now
