Given the below code PLEASE EXPLAIN ALMOST

LINE$-$BY$-$LINE HOW THE CODE WORKS TO ACHIEVE WHAT IS STATED

ON THE COMMENT SECTION BELOW.

Please have in mind the following:

ASCII HEX values of symbols $0-9$ are $030-039$

ASII HEX values of symbols A$-$F are $041-046$

When you are adding a number with no designation then it is assumed to be decimal, and so you would need to transform it to HEX if you are adding it with HEX in order for it to make sense. The more you explain how this code works like an Engine the needed result, the more partial credit you will receive. Use the LCI that were sent to you. This is one of the functions in it$.$
