I can’t tell if this guy is doing a bit or not
“Offensive humor” mfs when they listen to a comedian that tells actually offensive jokes.
Tangent time: This is how masculinity standards are bullshit. Bill Burr carries himself as just a guy, and the whole ‘not welcome at hooters’ line is literally weird alpha male code word for taking away his man card. Sorry, that’s always something that bothered me.
What even is the point of hooters? Just go to a strip club dumbass if you’re that horn
Can’t take my toddler to a strip club buffet because of woke!
His ass is not welcome at Hooters
bald
based, if we are talking about his recent antics
is he like cancelled cancelled? I’ve only seen 1 bit by him and he seemed cool

My brain works like
100 - 100*(10/100) = 90
90 + 90*(10/100) = 99
common core?Genuinely curious I am like 40 years old
Greek school. 37, so same age.
Ah I’m in US so maybe this is one of those rare occasions where the US took an actually good idea from europe. I hear it’s a better system.

I don’t think I was ever taught this, but that’s more or less how I do arithmetic. More precisely, my mental arithmetic would transcribe to:
47 + 36 = 47 + (30 + 6) = (47 + 6) + 30 = 53 + 30 = 83

I think they’re essentially the same thing. I don’t really have a process for what order to work in, just intuition for what will be the least friction. If it were big enough numbers I’d probably go through a second time in a different order of addition to double-check.
It’s just weird that I’ve done a lot of math and never really thought about that process. That’s why you’d ideally want any math below precalc to be taught by someone with a math education degree rather than someone who just has a math degree. When you’ve used the concepts you’re teaching with enough regulatity that they’re second nature, you have very poor intuition for which concepts will trip up someone learning for the first time.
Same, but instead of “*(10/100)” I just go: “drop the last zero”
You learn this pretty quickly when you bet on meme stocks. Down 90% then up 100% I can assure you, you are no where near where you started.
there are people who graduated high school with better grades than you got who think like this

At work I created a simple spreadsheet to help with a task where you have to add two values in a row together and then subtract a third and then round up to the next multiple of eight. All of these are whole numbers, most of which are less than thirty. A substantial number of the people I work with clearly struggle with it and I’m constantly finding mistakes from when they use it stemming from bad arithmetic.
Realizing this was actually what made me give up on organizing here more than anything else. If Americans can’t do first grade level arithmetic no wonder they’re so clueless as to how badly they’re getting screwed over.
people turning down raises because they don’t understand tax brackets
It’s also caused by vague wording. “Up 10%” can mean both: “up by 10 percentage points” and “a 10 percent increase”
I know that I’d only ever use it to mean “a ten percent increase” but colloquially, it can mean either. In a work email, I would make sure to specify which I mean.
This is exactly why they use basis points in finance discussions.

Uuh, I don’t understand the difference you are pointing
Basically, if a percentage goes up 10 percentage points, it is just an addition. “His approval rating jumped 10 percentage points from 24% to 34%.” There are 10 percentage points between those numbers.
If a value increased by 10%, it went up by 10% of its previous value. “The price of eggs increased by 10% from $9.00 to $9.90” the original value gets multiplied by 1.1
They aren’t talking about percentages in the original tweet, so this doesn’t really apply, but I think this vagueness confuses people so I prefer to be more specific than just “up 10%”
Ooh got it
“Fuckin’ magnetspercentages! How do they work?”honestly considering how many people get this wrong I don’t blame greg. I got this wrong until I got ranted at by a math wizz in uni, who I do thank. Shit’s unintuitive!
It makes much more sense when converted into fractions and multiply, where you have 9/10 and 11/10 respectively. Using percentages outside of a fixed reference causes all the confusion.
optimistic to expect your average peon, including me, to turn percentages into fractions in their mind
But, but… percentages are already fractions. Per cent = “out of a hundred”.
The % symbol even looks like a fraction to remind everyone.
Now, simplifying fractions from 90/100 to 9/10—in spite of it literally being removing a zero from each side—does seem to cause some real problems.
where you have 9/10 and 11/10 respectively
This is the one that is not intuitive
How are you at thinking about years, decades, and centuries?
If we take it step by step:—
- 10 years of a century is ten years out of a hundred.
- 10% is ten out of a hundred.
- So 10 years is 10% of a century.
Looking at the same thing another way:—
- 10 years is a also a decade.
- There are 10 decades in a century.
- So one decade is one tenth (1/10) of a century.
Bringing in the comparison from earlier:—
- 90% of a century is 90 years, or 9 decades.
- 9 decades is nine tenths (9/10) of a century.
- 110% of a century is 110 years, or 11 decades.
- 11 decades is eleven tenths (11/10) of a century.
Are these familiar enough to make sense as a parallel, or just further irrelevant confusion?

not a lot, usually
It’s not like I don’t get the train of thought here, it just doesn’t come intuitive

You are correct. It’s more like leaving off the Unit from a number, with that causing an incorrect conversion somewhere else.
I finally learned to convert fractions and imperial vs metric by selling drugs and working retail lol.
For example I can tell you that one OZ =
0.6250.0625* LB off the dome but don’t ask me to do calculus.one OZ = 0.625 LB
I think you’re missing a zero, or have transposed the zero and decimal point. You need 16 oz for 1 lb, right? Or did you just give your customers really good deals?
lol yeah meant to be .06 my bad. Of course that kind of oversight you would quickly realize while weighing stuff out
Oh, I never learned Oz to lb. Ounce just was some weird thing like 28 grams
But aren’t you german?
what’s your point?
The krautian brainpan imposes an adaptative tradeoff where it restrict the development of sense of humor in exchange for being good at nerd stuffThought your primary and secondary schools are still good, like well funded and still not teaching creationist science and stuff like that.
Like, in my last year of public secondary school more than half my class somehow struggled with speed * time = distance, but eh teachers get paid shit what can you expect
Sure, people can have dislexia or just not be good nor motivated at math , but it was more than half the class
Thought your primary and secondary schools are still good, like well funded and still not teaching creationist science and stuff like that.
Well it’s been a while. As far as memory serves all my math and physics teachers were pretty good. Just stopped clicking somewhen, I think I just got a terminal case of humanities brain.
If you’re getting outmathed by Andrew Yang, maybe sit numbers conversations out :/
gonna call my buddy Greg who is an expert in most numbers
Quick maffs
