Sure. But most people have forgotten such details long ago - negative
numbers are not part of daily life (except as an indicator of how much
you owe the bank...). After all, negative numbers are not natural!

Most people understand credits and debits.

From my experience, most do not. In particular, if you gave them
examples of a transaction and the relevant accounts, they would have no
idea which accounts should be debited, and which should be credited.

Sure, most people don't understand double-entry bookkeepping.  I was
thinking of simpler concepts.  Depositing money increases your bank
account balance, withdrawing money decreases it, withdrawing too
much can result in a negative balance, and so on.  A checking account
or credit card statement shows numbers with or without a "-" symbol.

Most of us here are probably in the top 10% of the general population
in terms of mathematical knowledge, and it can be difficult to know
how much knowledge most people have.  But I think that most people
have a decent basic understanding of positive and negative numbers.
As I mentioned recently, temperatures might have been a better
example.

And this is *way* off-topic.
