We need to subtract TB8446_11 from 11ebb939_4a4b_5fb5_9e6c_2b1ba8fba323. Starting from the rightmost digit, we subtract 1 from 11 and get 10. We write down 0 and carry over 1. 
Next, we subtract 1 from 3 and get 2. We write down 2 and carry over 1. 
Next, we subtract 4 from 6 and get 2. We write down 2 and carry over 1. 
Next, we subtract B from 4 and get 3 (since B is equivalent to 11 in hexadecimal). We write down 3 and carry over 1. 
Next, we subtract 4 from 9 and get 5. We write down 5 and carry over 1. 
Next, we subtract 9 from 3 and get -6 (borrowing 1 from the next digit). Since we are working in hexadecimal, we write down A (which is equivalent to 10 in decimal) and carry over 1. 
Next, we subtract B from B and get 0. We write down 0 and carry over 1. 
Next, we subtract 8 from 9 and get 1. We write down 1 and carry over 0. 
Next, we subtract 4 from 3 and get -1 (borrowing 1 from the next digit). Since we are working in hexadecimal, we write down F (which is equivalent to 15 in decimal) and carry over 1. 
Next, we subtract 6 from 8 and get 2. We write down 2 and carry over 0. 
Next, we subtract E from 4 and get -A (borrowing 1 from the next digit). Since we are working in hexadecimal, we write down 6 (which is equivalent to 10-16=-6 in decimal) and carry over 1. 
Next, we subtract 1 from 1 and get 0. We write down 0 and carry over 0. 
Finally, there is nothing left to subtract, so we write down TB8446_11. 
Putting it all together, we get 11ebb939_4a4b_5fb7_9e6c_eb8de836482d_TB8446_11.
