More specifically, can you explain the joke? Why am I not worrying (but secretly worrying) about this guy with DNA tests almost the exact same every time?

The rules are universal, only the mnemonics used to remember the rules are different

The rules and the acronyms describe different things. If you have to make more rules to say M and D are the same, and that you go left to right when you do them, then the basic rules you followed were flawed. The universal conventions of mathematics don’t need these acronyms confusing people.

high school Maths textbooks

I haven’t seen anything since early elementary school, not middle school, and certainly not high school. Regardless, if a textbook has it, it doesn’t make it right at all. If the acronyms are useless to learn, having them in a textbook doesn’t validate them.

and order of operations worksheet generators

…that’s one of the two examples you used? Did you think about that before you typed it out?

It’s always 2. #MathsIsNeverAmbiguous

IT IS AMBIGUOUS IN THIS POST AND ALL EXAMPLES I HAVE SHOWN. That is the problem at hand.

There is no real problem solving in trying to decipher poorly written shit. It’s the equivalent if English classes took time out to give students worksheets with “foder” written on them, and expecting students to find out if the writer meant “folder” or “fodder”- no sentence context, just following a list of “rules”. It is not difficult to write mathematical expressions with clear context to how numbers relate, even with the lazy shortcuts and shorthand that mathematicians love.

If you have both multiplication and division then you do them left to right. PEMDAS doesn’t mean multiplication first, nor does BEDMAS mean division first. It’s PE(MD)(AS) and BE(DM)(AS) where the bracketed parts are done left to right.

You are adding more rules to protect a convention that doesn’t work and doesn’t mention them to begin with. If all that matters is higher orders first, then why bother having an acronym? Just say “Brackets, then higher orders”. Bam. Solved it with less words than any of the acronyms.

Left associativity means it always operates on the following term. i.e. terms are associated with the sign on their left.

As someone who studied mathematics, computer science, and engineering in university, I certainly don’t you to tell me how to do bare bones arithmetic. I know operators apply to the numbers to their right. Everyone does. You jumped right on by the point.

With 2/2*2, you don’t know if it is 2*2/2, or 2/(2*2). When you are dividing by numbers, you put them all in the denominator. If I had to put it in a line, I would at least do 2/(2)*2, to show what is in the denominator. If it is ambiguous, you have done it incorrectly.

By the rule of left associativity.

BY CONVENTION, as I said. You don’t have to repeat what I said a second time.

No it doesn’t. How on Earth did you manage to get -2?

wow. geez. I wonder.

If you can’t follow the steps guided for such a simple example, maybe we just shouldn’t have this conversation. It’s not like you could have tried in your head different orders to combine 3 numbers.

Of course it is with age. No mammals are born lactose intolerant. We drink milk as infants.

Almost universally, all adult mammals become lactose intolerant. We humans are lucky for those of us who tolerant.

Yes, the fundamentals the same, higher orders come first. BUT…

-Multiplication comes before division in some forms, like PEMDAS. In the example I use, this changes the answer.

-When you apply an operation, you should specify what it is operating on. In all of these acronyms, addition comes before subtraction, but with a different example:

2 - 2 + 2

The minus sign only applies to the middle term, by convention. It is the equivalent of “adding negative two”. You can quickly see that this expression is equal to 2.

But if you use one of these acronyms, you end with this expression evaluating to -2. I would say it is almost universally accepted that 2 is the correct answer, and -2 is incorrect. Basically, all these acronyms end up being useless waste of time.

I don’t know if I conveyed this the first time, but, as a lover of pure mathematics, this is something that does not have application in life or in study. It’s an utterly useless waste of time. There is never a case where someone give you numbers like this, where it is not clear what order the numbers should be applied in.

Even your “BODMAS” isn’t universal, lots of people learn “PEMDAS” or “BEDMAS”

At any level of mathematics after elementary school, you never see terrible expressions like this. Well, except for facebook and twitter

Take for example: 2/2*2 It is 0.5 or 2 depending on order. But if I were anything after high school (I was more complacent in high school, I guess) if someone gave me an arbitrarily solved equation or expression like this, I would be livid and raise hell at them for trying to do that.

The part directly above the species is the genus. Family comes after that, and is Cannabaceae in this case.

wtf is KAPWING and why is that text so much bigger than the meme?

The conspiracy is growing.

No, dude, they are making fun of themselves. The joke is Dull has access to revise the changelog, hid an oopsies, then “self reported” and wrote “literally 1984” on it.

Left side, original patch notes: “Fixed our rate limiter that DullBananas broke”

Right side, DullBananas revised version: “Fixed our rate limiter <full stop>”

“Literally 1984” because they are censoring the TRUTH.

ELI5 plz

If your version of “fun” is repeatedly showing everyone the stupid thing you posted last time you were stoned out of your mind and telling them it’s a great mnemonic or mantra, then I’mma have to ask for us to not be friends.

The Fahrenheit scale was built around human biology.

Nope, it was built around the highest and lowest extremes some dude could create in his room. Not based on human biology in the slightest. Don’t repeat this false information.

0C isn’t even that cold, and 100C is literally instant death.

Yeah, but counter argument, who gives a shit? The “meme” doesn’t say anything remotely close to “from 0 to 100”. I don’t know why you are under the impression that these scales become inaccurate if you leave the 0-100 range. I live in a region that frequents -40C to +40C over a year- that’s centered on zero, so it’s already better for “how humans feel” than being centered on 32 and pretending there is some cosmic/celestial/god ordained reason for it.

Kelvin is the most scientifically objective scale, but also the least intuitive for humans…

Still no one giving a shit- the “meme” doesn’t remotely even suggest anything related to this.

Be forewarned that I am willing to die on this hill

I don’t know why you sign this off with “I’m an obnoxious twat”, but I’m perfectly happy with using the block function if the threat is real.

“Kilometres is how cars drive. Feet is how people run”

This has the same level of nuance and thought behind it. It’s just stupid.

Nah, it doesn’t make any sense, and isn’t deep or insightful at all.

That is such a great image for memes, I’ve never seen it before.

This was me for a long time, and a pretty big symptom of depression.
