I still remember my teacher bitching me out in front of the class when we were learning negative numbers because when he asked me how I figured out the correct answer I said that the positive numbers and negatives cancelled each other out. Like -4 and positive 5, the negative 4 cancels out 4 on the positive side and you are left with 1. Maybe that wasn't the correct verbiage but it gave me the correct answer every time. He was a dick about correcting me though.
You understood numbers intuitively and that piece of shit could not even comprehend that someone can understand it this way.

So, there is some jank in how Microsoft handles the desktop that results in more shortcuts on in using more resources. It always has to have all the images and icons loaded at all times.
But with the increases in baseline RAM I'd be shocked to find anyone with more than 4GB experiencing slowdown from it, even in the most extreme situations.
Similar thing with trash/recycling bin. Are you already low on storage space? Then yeah, clean it so your PC has enough spare space to work, or to use for swap (effectively extra, slower RAM by way of using drive space). But that was also far more likely to be a problem on the old drives measured in MB.
Yep, too many icons was a thing in Win95 in 98. Can't remember if XP cared.

There’s not much worse as a kid in a learning environment, or even with your parent(s), to be shut down painfully for being right about something that they don’t know or don’t think you know. Really crushes the satisfaction of nailing a win and turns it into bitterness and starts the lifelong process of keeping your mouth shut when you’re right and letting others win when wrong.
So the school did its job just right then. High five, I quietly let people be wrong too.

I had a math teacher who yelled at me for solving equations with a different method. I didn't understand his explanation so I asked my brother for help. He taught me a more advanced method taught in a higher grade, which was easier, but I was not supposed to know that method yet. The teacher told me to redo everything but when I asked for help he told me to ask my friends. So, I just copied everything from my friend and then submitted it.

Flashbacks to shitty math teachers. It was either this or "WHY DON'T YOU KNOW THIS YET!?" I quit participating and made a C for the rest of my academic career including college. I also got "I don't how you got this answer, but it's the right answer." . Hell I don't even know how I got that right answer but I refused to ask questions.
-
All my teachers were fine with it honestly :3 at least after primary school.. if you corrected them they might've given you extra credit
But the general notion of saying something correct and people saying that that's wrong, and not knowing why still stands
You had an extraordinary school experience.

Ah I recall my "science" teacher when I was 13 explaining to us that all materials expand when heated and shrink when cooled.
So I ask how ice floats, or how ice cubes swell above the tray.

(I don't think that was your teachers point at all, but) couldn't the different formulas have produced different rounding errors due to floating point percision?
Doubtful, but if anything mine would be more accurate. Fewer calculation steps to lose precision on. I think most spreadsheet software fudges floating point precision anyway. A computer programmer may accept that 0.1+0.2 is not 0.3 but an accountant or mathematician would not be having it.
I think she was just shit at maths tbh. As a kid you sort of assume all the teachers know more than you about every subject, and that's not the case at all.

Excel has a 15 point float, a quadrillionth, which should be enough for anything you were using excel for.

Maybe :3 I think my school wasn't that highly ranked nationally, but I don't know how others were in terms of the teachers so can't compare.. It definitely had a lot of other issues tho haha

School really does prepare you for real life sometimes, it seems ...

I actually kind of believe it, because kindergarten/elementary teachers are often from arts & humanities backgrounds, and it's not at all rare to find one who never passed a high school STEM class and therefore prone to get flustered easily when called upon to explain the reasonings behind even simple things.
Can you fail all your STEM classes and graduate high school?

yeah because excel does rounding stuff automatically for you
try entering
0.1 + 0.2 - 0.1 - 0.2 == 0.0in any programming language of your choice and see what happens. -
Fucking hell I feel validated rn, I had a similar experience at that age but it was in language/reading class. It's so frustrating to know that you are correct but you lack the terminology/ability to properly convey why you are right.
if you had had the terminology to say it, they would probably just have gotten angry anyways over being exposed in class.

I had an elementary school teacher who insisted that gravity came from the earth's rotation, and that if the earth stopped spinning there would be nothing holding us down.

it kinda baffled me how people would even think that way

Yep, am autistic, can confirm.
As with Union of Kobolds, I eventually got into the 'gifted' program... they even had me as a 2nd and 3rd grader basically being an unpaid tutor for 4th and 5th graders, sitting in the hallway, helping kids with reading difficulties (in all liklihood, undiagnosed dyslexia) read through kids books.
But, there's always classes and teachers not part of the gifted program, and they're often difficult and wrong and rude for no reason.
I still remember a chemistry teacher getting very angry with me for even bringing up quantum scale electron clouds as a model of atoms.
Not allowed to go beyond the Rutherford-Bohr model, even in discussion, always dismissive and rude, incapable of saying just 'yes that is a more accurate model, but it is far too complex to go over without understanding Rutherford-Bohr first'.

Yeah, turned me off to science at that age too which sucks because I was pretty into it.
in case you still care: the periodic table is arranged primarily by the chemical properties of its elements (mainly electronegativity, i.e. how much energy it takes to add/remove an electron to/from the atom) and also by their mass.

Depends on how your mathematical system is defined. In the mathematics system this teacher is using, negative numbers simply do not exist. The answer to 5-6 is the same as 5/0: NaN. Is this mathematical system incomplete? Yes. But, as has been thoroughly proven, there is no such thing as a complete mathematical system.
I was under the impression that there is in fact such a thing as a complete mathematical system (if you take "mathematical system" in the broader sense of "internally consistent system"), but such a system would be pretty limited and therefore rather useless.
-
My experiences were to answer correctly, and then they go 'well, yes', and then don't ask me questions in the future.
same. i guess they want to make sure to ask people who don't already know everything, sothat everybody has a chance of learning.
