The Ogwife volunteers
at our church for any number of things, and sometimes the help she gets, while ambitious, is not… adequate.
Today she had a co-volunteer who was still attending college in her thirties become flummoxed at being faced with the task of making change for $25 out of $40.
Oy.
Long before there were pocket calculators I was taught at school and by my mother the bookkeeper how to check my work by casting out nines. Anyone who hasn’t ever done this, it seems like magic. And it is not foolproof but a bookkeeper who is entering data into a general ledger (How all business was conducted until the 70’s, pretty much, and even after that, for a lot of companies) it was a quick and dirty way to check your work. Remember that in those days only the head bookkeepers and accountants would have been supplied with adding machines, when the salary of a secretary was $20-$30 a week, an adding machine cost $300.
I get that you don’t need to do this because the machines are so much better and faster, that’s a very good thing. But shouldn’t anyone be able to make change for $25 out of $40?
