## Homework Statement

Hi all!

You are given the hex 9AB. I need to go from sign and magnitude of it, to it's two's complement (in 13-bit).

## The Attempt at a Solution

What I did was convert the hex to binary:

0100110101011 <-- I added an extra 0 for the 13th bit

I then flipped the digits, and added "1" and got this:

1011001010101

The answer to this is supposed to be 2475, and I'm not getting that. Would appreciate any help anyone can give.

Thanks.
