I will reply more to this subject. But. Nobody seems to know anymore what an inch is? The Dutch translation for inch is Duim/Thumb, which gives more feeling for this unit of length.

A Shelby Cobra running on 4 cylinders. 😉
We had the same issue- My son couldn't do subtraction in the 2nd grade and frustration was winning. Convoluted is the right word for their methods. I showed him a number line and taught him how to subtract by adding a negative number and he got it in about 5 minutes. I was ready to go to jail over it too, Bob. Home schooled grades 6-8.
Or an AC Ace with two misfiring cylinders. 😀
One of the things that drove me nuts (still drives me nuts) about the American K12 system is that the powers that be make seemingly random changes to teaching methodology, testing methodology, and course content.
The sane thing to do would be to study school systems all over the world, find out which countries have education systems that work really well (Denmark and Finland, for instance), and then implement the same good ideas they're using.
Instead, we usually see sweeping decisions applied with a heavy hand, decisions usually made by politicians with no apparent input from the the researchers who actually study education, and the educators who actually implement it and see how it's working in real classrooms with real students.
I have had to do exactly the same thing, too many times over the years - with adult students aged 19 - 21 years old...😱
And let's not even bring up fractions. Of all the mathematical concepts American children and young adults are confused about, fractions seem to be about the worst. I really think everyone would be far better off if they just taught decimals for several years in elementary school.
Decimals are fractions done right - a decimal number is just a fraction whose denominator is always an integer power of 10, rather than random numbers like 3 or 4 or 17. 🙂

Your lack of English language skills has caused you to be offended when no offense was intended. This is blatantly obvious to any native speaker of English.
So now you are ignoring someone who simply said that it is a "pet peeve" of theirs when precise language is not used in such riddles. It was not a personal attack.
Also, he did a good job trying to explain why the language that you used in your riddle is dubious, but you have simply ignored that.
You had an opportunity to learn a very important lesson about English (and logic) but you chose to be offended instead.
Well done.

I bought some dog treats yesterday. My wife noticed a flyer at the checkout counter and alerted the (early 20s?) clerk that the dog treats were 20% off.
"Oh, no, that's for a different size - it's for 780 grams" said the clerk. (The flyer text listed it as "780g bag")
I was only half paying attention, so I paid and my wife and I were about to leave and then I looked at the bag. It clearly showed 0.78kg (it also listed it in pounds/ounces).
The clerk had already left from the till and was standing with her (early 20s?) co-workers. We walked over to them and I said, "This is actually the 780 gram bag."
She said "Oh, let me see..." (I showed her the bag again) "... but that's in kg."
"Yes. 0.78 kilograms is precisely 780 grams." I said.
"Oh... really?" She clearly did not believe me. The other staff stood there looking daft.
She took the bag to the counter and compared it to the bag in the flyer photo. She pulled the flyer up close to her face and said "Oh you're right, it even says that on the bag in the photo."
I politely thanked her after she refunded me my $4.48. She looked extremely doubtful even after all of that. How could it be possible that 0.78kg is the same as 780g?

Dude, that was a total Instagram story moment - ah well, I suspect the opportunity may yet present itself again.
Indeed.
I was saying to my wife later - when I am another decade or so older I'll be "that guy" who pulls out a pencil and notepad and shows the clerk the math.
I'm actually not very good at math. I always hated it in school. How the hell can these kids know less than I do?

It was by no means a riddle. Only elementary math.
Thank you for teaching me to live, great teacher.
The little grasshopper appreciates your immeasurable wisdom.
I consider that one of the most miserable acts of people is "to make firewood from the fallen tree".
" Hacer leña del árbol caído "
No one has requested your opinion.
But, this tree is standing, and you have the problem that "the tree prevents you from seeing the forest"
" El árbol muy cerca no deja que se vea todo el bosque "
I hope that the translation of GT is understood, but copy it, paste it, and find out on the web, they are universal and very common sayings in my language.

You may have been focused on the elementary math, however your poor choice of words made it a riddle, and the answer that you provided was wrong. Please see the above Master/Student examples so that you can understand precisely why.
I suspect that it works exactly the same way if translated to your native language.
rdf tried to explain this and you put him on your ignore list. Do you always immediately shut out people who try to help you?

Not the same but related: when I watched Politician´s ads and speeches on TV, I asked **my Mother** (a regular Housewife, not an University teacher or equivalent) what she made out of them.
Typical answers were "that Woman has some balls indeed" or "that Guy is really handsome and smart, his moustache makes him serious and intelligent".
ZERO opinion on the actual event which was being discussed.
Trivial anecdote?
Not so sure, "She" became our Ministry of Interior, commanding all our Security Forces (Police, Coast Guard, etc.) and "He" became our last President 😱
So if grown ups with good Social standing and good Education can be so naïve and malleable, I for one can not blame Young Ones for being so.
No, no, you still don't understand! I did not provide any answer to anyone! I put a story of something typical in many people, just that!
But it seems that you want to argue because you have felt alluded to by something that I ignore and besides, I am not interested. Your problem, friend .... And if you want to "fight"! Don't count on me, children ....
I attached what I exposed first and you and rdf then repeat as a parrot what I put clearly in universal mathematics!
Look and study this well (post 181) or go back to elementary school, or admit that you are mixing "pears with apples".
I wrote:
More than once I meet graduates of university studies who are challenged to add and subtract percentages and always fail at the same step:
You have 100 and you add 10 percent, how much is it?
110! They responded quickly.
Well, and now to those 110 take out the 10 percent you added, how much is it?
Almost always, they are wrong answering 100!
The correct result is 99, because the percentages can not add or subtract directly!
A few years ago, researchers in the USA found out that the most accurate predictor of an election candidate's success was his/her campaign photograph. Not the candidate's achievements, education, previous political history, opinions, political platform, none of that. Only his/her face. 😱
More of that article here: A candidate's looks count for far more than voters like to believe | Leonard Mlodinow | Opinion | The Guardian
While the physical appearance of competency wins US elections when normal candidates run for office, there must be different subconscious rules at work in some special circumstances with some special candidates. Surely it cannot have been the appearance of competency that led the USA to the pickle it's currently in?
So yeah, the evidence is that large groups of people often do fairly stupid things and make fairly stupid collective decisions. Nothing new there. This particular thread is to discuss the question of whether we've begun to do even more stupid things in recent years. 😀
Such as, for instance, naming a Royal British research ship "Boaty McBoatface": 'Boaty McBoatface' tops public vote as name of polar ship - BBC News
So far this thread has been about declining cognitive and functional abilities of people in recent decades, something I have seen considerable evidence for over the years. I would submit there is a second parallel trend: declining mental age, i.e. a huge global rise in the psychological condition known as "arrested development", in which a person's mind remains childlike and immature even as their body grows up and turns into an adult.
In cases of arrested psychological development, the mental age of the affected individual remains much lower than their physical age, so that, for example, you might see 25-year-olds who think it's cute to wear fuzzy animal costumes, big furry animal ears, or back-packs shaped like teddy-bears or monkeys.
The "Boaty McBoatface" fiasco is a classic example. It is exactly what I'd expect - completely normal - if a group of, say, seven to nine year old children were asked to chose the name of the research ship, and given "Boaty McBoatface" as one option. Childish and silly, but seven year olds *are* children, and of course they're childish.
What makes it shocking is that this idiocy came from adults, and not elementary school children. That's deeply disturbing. The continued existence of democracy itself, and all the vital social and cultural institutions that keep us from descending to savagery, depends on the votes of these same infantile people - does not that scare the heck out of you?
Looking at it from another angle to get some perspective, can you imagine adults from your great-grandparent's generation being immature enough to to name a brand new national scientific research ship "Boaty McBoatface"?
I can't. That generation wasn't suffering from widespread arrested development, so they wouldn't find something so childish appealing, any more than they'd want to spend their entire Sunday bouncing up and down on a spring mattress.

I can't imagine them having enough of a sense of humor or irreverence to do so, no. Too bad for them, the old sticks in the mud. 😛
The language barrier must be the problem. You still have no idea what I have actually told you.
Forget it. I now realize I am wasting my time.
The intent of your post 181 question is correct - of course subtract 10% from 110 and you get 99.. but semantically your example is incorrect and misleading because of the phrasing of the question. It implies that you are subtracting the resultant of the previous operation instead of performing a new distinct percentage change operation.
The '10 percent you added' was the number 10. So you are effectively saying 'subtract 10' when you mean subtract 10%.
The others were trying to help you to understand their reasoning and how the English phrasing isn't correct but you reply with condescending and argumentative language when I personally don't think there was any ill intent toward you.
If you expect adults to have the same sense of humour as a small child, sure, that's how the situation appears.
But in a normal world, an adult brain is quite different from a child's brain, quite literally, right down to the physical wiring of neurons. Not surprisingly, in a normal world, an adult's sense of humour is very different than a child's...
Take, for instance, the writings of P.G. Wodehouse, about a century ago. He had millions of adults and teenagers laughing till they doubled over and wheezed, all around the world - but not small children.
Little kids didn't find Wodehouse funny. No fart jokes, no "Boaty McBoatface", but rather, unexpected turns of phrase, ludicrously out-of-place literary references, and improbably ridiculous perils. Stuff small kids wouldn't "get".
However, decades ago, little children were hugely entertained by "Itsy Bitsy Spider", but adults were unlikely to guffaw with laughter at the thought of a spider stalking up a drainpipe and repeatedly being washed back down.
We are no longer in a normal world, and now many adults have childish minds, and childish senses of humour to go with them. Itsy Bitsy Spider might go over very well with the people who voted for "Boaty McBoatface". Heck, "Itsy Bitsy Spider" might soon become a major motion picture at your local movie theatre, or maybe on NetFlix, right up in the pantheon of great comedy, with "Dumb and Dumber" and "Zoolander". 🙂
Adults watching "Itsy Bitsy Spider" will be encouraged to snuggle into a leopard-print "onsie" fur-fabric animal costume, and suck their thumbs while watching, for the full adult experience, circa 2020...
