Is it possible that Polish notation was entering into things somehow? BTW, for years I though the term ‘Polish notation’ was a derogatory term, as in a Polish joke…
Another weird one, to American ears, is using “upon” instead of “over” for fractions. 5/8 is “5 upon 8”. Seems to come up whenever I interview Indian candidates.
See posts 8 and 16. (He meant RPN, of course, not RPM – Reverse Polish Notation.)
There’s an unintentional Polish joke in there somewhere, if you dig deep enough. Spoilered because, y’know, maybe offensive to the Polish? (Where’s the VB code for [rot13] . . . [/rot13] like we used to do in the Usenet days?)
[spoiler]Polish notation was so-named after its inventor, Jan Łukasiewicz. His notation involved putting the operator first, followed by the two operands, e.g., + 3 4 instead of 3 + 4. This notation turned out to be massively useful in Computer Science, except that it turned out most useful to put the operator afterward, thus giving us Reverse Polish Notation, or RPN: 3 4 +
RPN is so standard in CS today that it should be called Polish Notation. Mr. JŁ, in inventing his Polish notation, got it backward. We should be calling his original notation “Reverse Polish Notation”. That’s the irony there. That’s why there’s a Polish Joke buried in all of this.[/spoiler]
ETA: And why do we name innovations after the country the innovator came from instead of just, y’know, naming after the innovator? Is it because nobody knew how to pronounce his name? Same with Hungarian Notation, named after Charles Simonyi.
Either your father was wrong, or you’re misremembering.
I never bother to calculate RPM, I just look at the tachometer.
BTW, my parents, born in the mid 20’s, would generally use “minus”. My mother’s father, a doctor who’d taught elementary math plus GI bill to fund his education, used “from”. If they’re typical, then usage changed in the first couple decades of the 20th.
My grandfather wasn’t typical in many ways though, so who knows.
Well i have the answer, 8-10=2 simple :)
You said he is “from a Mediterranean country.” Was he taught in another language (maybe even in New York)? Besides confusing “from” or “less” and “minus” in English, maybe he is thinking in a language that uses (or used, when he was growing up) a cognate of “minus” the way we use “from.”
It wouldn’t even have to be a cognate. People who speak multiple languages , even very fluently , sometimes have context-limited vocabularies. My husband speaks Cantonese fluently and without an accent, as he learned it simultaneously with English as a child. But his schooling was entirely in English and his Cantonese vocabulary was limited to what was useful in everyday life- no specialized vocabulary for contexts that he didn’t normally discuss in Cantonese. And “minus” is really part of a specialized vocabulary. I mean, I don’t know about anyone else, but when I’m subtracting in daily life I don’t normally use the word minus. It’s “I started the day with two hundred dollars and spent $57.50 so I should have $142.50 left” or “My share of the bill for the party is $2500 , but I paid $800 to the DJ so here’s $1700.” When I write it down, it’s 200-57.50, but the word “minus” isn’t used when I’m thinking (even aloud) about it.
My grandmother (born in 1912) went to school in New York City. She never approached subtraction as described above, as far as I know.

I think your father might have misremembered or reversed things.
There’s one other possibility that hasn’t been mentioned. Is your real name Calvin? Maybe your dad was messing with your head.
That might be possible too. He emigrated when he was quite young. All of his schooling was in New York in the English language.
His parents knew some English but I suspect that he mostly spoke his other language at home. When I knew him, he spoke English like a native (except when he was pandering.)
So he would have been educated in English, in the style of the times. But it’s possible that he confused “less” with “minus” due to some mental translation.
