Use summation rules to compute the sum.

The summation rule states that when adding hexadecimal numbers, if the sum of the digits in a column is less than or equal to 15, then the sum can be written as a single hexadecimal digit in that column. Otherwise, the sum must be written as two hexadecimal digits in that column, where the digit on the left represents the "carry" from the previous column. Applying this rule to the given sum, we have:

1  1  e  a  a  8  8  b
+    9  1  a  d  _  a  c  c  3
-----------------------------
    11  3  8  8  _  2  6  6  b

Since the sum of the digits in the sixth column is not greater than 15, we can simply write the sum as a single hexadecimal digit (6) in that column. The answer is therefore 11eaa88b_91ad_acc4_a696_29dd53da81b9_TB5869_11.
