To evaluate the function, we need to add the first two hexadecimal numbers together and subtract the third hexadecimal number. 
11ea99db_b6c5_b866_94ac_d3f2baebd59c_TB4590_11 = 11ea99db + b6c5 - b866 = 11eb2e60 
11ea99db_b6c5_df77_94ac_e716efd6bc97_TB4590_11 = 11ea99db + b6c5 - df77 = 11e80c3f 
Now, we subtract the third hexadecimal number from the sum of the first two: 
11ea99db_b6c5_df78_94ac_01f82a59ee72_TB4590_11 = 11eb2e60 - df78 = 11eabde8 
Therefore, the answer is 90.
