Welcome to the 21st century. We have this thing called the internet so people can share information without killing trees. It’s the resource material for a college course. That’s like the definition of a text book without costing the students a month’s rent.
random people.
One is a PhD teaching a college course on the subject, the other is Wolfram. Neither of those are “random people” and I’m willing to bet their credentials beat “claims to be a high school math teacher” pretty soundly.
I already pointed out to you that they DON’T teach order of operations at University. It’s taught in high school. Dude on page you referred to was teaching Set theory, not order of operations.
This portion of the discussion wasn’t about order of operations, it was about the number of inputs an operator (+, and - in this case) has. Try to keep up.
Don’t know who you’re referring to. I’m a high school Maths teacher, hence the dozens of textbooks on the topic.
Dear God if that’s true I feel sorry for your students and embarrassed for whatever school is paying you. But this is the internet and with any luck that’s a flat out lie. But at least your repeated use of the plural maths means you’re not anywhere near my kids.
And yet the textbook says nothing of the kind. If I had 2+3, which is really +2+3…
Oh, I see the problem. We’re back to reading comprehension. That section you highlighted specifically refers to when those symbols are being used as a “sign of the quality” of the number it’s referring to, not when it’s being used to indicate an operation like addition or subtraction. Hopefully that clears it up. This is ignoring the fact that a random screen shot could be anything. For all I know you wrote that yourself.
do I, according to you, have to write 0+2+0+3
No. You also don’t need to write +2+3 because the first “+” isn’t an operator. It’s, as your own picture says, a sign of the quality of 2.
Now you’re getting it. Multiply and divide take 2 inputs, add and subtract take 1.
I would love to know how you get to a sum or difference with only one input. Here, I’ll try to spell it out using your own example so that even you can understand.
The inputs to 2 + 3 = 5 are 2 and 3. Let’s count them together. 2 is the first, and 3 is the second. 1, 2. Two inputs for addition. Did you get it this time? Was that too fast? You can go back and read it again if you need to
Actually none of those are operators. The first 2 are grouping symbols
Fine, operation then. The fact that you think “!” is the same thing as brackets doesn’t do anything to help your bona fides. And I don’t have the energy to write up a word doc and screen shot it since that’s apparently what it takes for you to consider something valid.
Maybe you’re just being weirdly pedantic about operator vs operation. Which would be a strange hill to die on since the original topic was operations.
You very nearly got it that time though! 😂
If by “it” you mean through your thick skull, then you’re more optimistic than I am.
Again, it’s not me who’s wrong.
Again, it is. I could keep providing sources, but I still don’t have the time to screen shot some random crap with no supporting evidence.

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: 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.
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.
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. With 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. 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.
- Comment on A fake Facebook event disguised as a math problem has been one of its top posts for 6 months 1 week ago:
The arithmetic operations, addition + , subtraction − , multiplication × , and division ÷
That better? Or you can find one you like all by yourself: 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.

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 he contends it should be.

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 (konstakang.com/devices/rpi5/LineageOS22/) as an option. Then you can still use whatever SW the phone would have had on it.

Technically there shouldn’t be any major problems with your plan.
