Nope. It’s still not a textbook. Sounds more like a higher education version of Wikipedia.

It is though. Here’s a link to buy a printed copy: https://libretexts.org/bookstore/order?math-7309

You keep mentioning textbooks but haven’t actually shown any that support you. I have. I’ll trust the PhD teaching a university course on the subject over the nobody on the internet who just keeps saying “trust me bro” and then being condescending while also being embarrassingly wrong.

I’ll also trust Wolfram over you: Examples of binary operation on A from A×A to A include addition (+), subtraction (-), multiplication (×) and division (÷). Here, you can buy a copy of this too: https://www.amazon.com/exec/obidos/ASIN/1420072218/weisstein-20

The average intern there has probably forgotten more about math than you will ever know.

Says person who doesn’t understand the difference between unary and binary.

Talking about yourself in the third person is weird. Even your nonsense about a silent “+” is really just leaving off the leading 0 in the equation 0+2. Because addition is a binary operator.

Apparently EVERYTHING is binary according to you (and your website). 😂

Only the ones that operate on two inputs. Some examples of unary operators are factorial, absolute value, and trig functions. The laughing face when you make a fool of yourself isn’t really as effective as you think it is.

But we’re getting off topic again. I can’t keep trying to explain the same thing to you, so I would say this has been fun, but it’s been more like talking to an unusually obnoxious brick wall. Next time you want to engage with someone try being less of a prick, or at least less wrong.

Actually, it is. Written by a PhD and used in a college course. It just happens to be distributed for free because Canada is cool like that.

May want to work on your own reading comprehension.

It’s not me who doesn’t understand the difference.

The facts disagree.

You can keep saying defined all you want, it doesn’t change the underlying issue that it’s defined by man. In the absence of all your books (which you clearly don’t understand anyway based on our discussion of unary vs binary) order of operations only exists because we all agree to it.

The arithmetic operations, addition + , subtraction − , multiplication × , and division ÷

That better? Or you can find one you like all by yourself: https://duckduckgo.com/?q=binary+operator&ko=-1&ia=web

Yes it does., need to work on your comprehension…

And you can shove the condescension up your ass until you understand the difference between unary and binary operators.

But to original point. I’m not disagreeing with anything and you’re proving my point for me. There is no fundamental law of the universe that says multiplication comes first. It’s defined by man and agreed to. If we encounter aliens someday, the area of their triangles are still going to be half the width times the height, the ratios of their circles circumference to diameter are still going to be pi, regardless of how they represent those values. But they could very well prioritize addition and subtraction over multiplication and division.

Typical examples of binary operations are the addition ( + {\displaystyle +}) and multiplication ( × {\displaystyle \times }) of numbers and matrices

Very confidently getting basic facts wrong doesn’t inspire confidence in the rest of your comments.

Your example still doesn’t give a reason why 2 + 3 * 4 is 2 + 3 + 3 + 3 +3 instead of 2 + 3 + 2 + 3 + 2 + 3 + 2 + 3 other than that we all agree to it.

But +, -, *, and / are all binary operators?

As far as I know, the only reason multiplication and division come first is that we’ve all agreed to it. But it can’t be derived in a vacuum as that other dude contends it should be.

Technically possible or not, that seems like a great way to get your account shut down.

You’re right. When you’re doing it for commercial gain, it’s not fair use anymore. It’s really not that complicated.

I have Twitter blocked at my router.

Please tell me one of the “politically incorrect but objectively true” facts was that Elon is a pedophile.

If we’re going to Iran anyway, the least we can do is send these assholes in first.

Isn’t brave’s whole thing just replacing ads with their own ads? I’ve never understood why people bought into it so hard.

MythTV is the OG.

Don’t forget decorator crabs.

I have a 25yr old PII that TinyCore runs just fine on.

Palantir will be playing the role of IBM in this reenactment of fascism.

That’s the best case.

I’m thinking thalidomide.

If you just want to keep track of your bookmarks using git, floccus can do that.

You understand that gen x starts around 1965, right? Your stat says they’re mostly getting fucked too.

Isn’t that basically what commas are for?

I admittedly didn’t look super closely at the projects that have been linked, but my guess would be that the phone can be replaced with SW on the Pi. Something like volumio that was linked, or Navidrome for music.

Mapping was always kid of a mess when I looked at this kind of thing in the past, and I don’t think it has gotten any better.

If it’s the phone hardware you don’t like, rather than the software, there’s always LineageOS on a Pi (https://konstakang.com/devices/rpi5/LineageOS22/) as an option. Then you can still use whatever SW the phone would have had on it.

What fundamental property of the universe says that

6 + 4 / 2 is 8 instead of 5?
