<p>To whom it may concern...

<p>To whom it may concern, </p><p>I'm trying to explain an old method of addition that is referred to in a text (unpublished) writen by someone who is no longer with us - therefore I can't ask them to clarify. The text states "...they could take a column of figures about five figures wide and about ten figures tall and add them up in a peculiar way, some kind of a crisscross addition and they would arrive with almost an immediate answer." </p><p>The author himself didn't know the technique well, but saw it done and stated roughly what he recalled the person (who did it) saying "Nine added to something gives you itself, so all you do is go down the column and find all the combinations which make nine and forget those, and add the remainder and you get the total." If this example throws you off, forget it. I don’t know the accuracy of it. However, it seems there is an old method to quickly add a column of numbers that seems to be a crisscross method and that's what I'm looking for. </p><p>Any help I can get in understanding this method, I would greatly appreciate!</p>
