Actually, it is. Written by a PhD and used in a college course.
Yeah there’s an issue with them having forgotten the basic rules, since they don’t actually teach them (except in a remedial way). Why do you think I keep trying to bring you back to actual Maths textbooks?
May want to work on your own reading comprehension.
Nope. It’s still not a textbook. Sounds more like a higher education version of Wikipedia.
The facts disagree
With you, yes.
it doesn’t change the underlying issue that it’s defined by man.
The notation is, the rules aren’t.
In the absence of all your books (which you clearly don’t understand anyway based on our discussion of unary vs binary)
Says person who doesn’t understand the difference between unary and binary. Apparently EVERYTHING is binary according to you (and your website). 😂
order of operations only exists because we all agree to it
It exists whether we agree with it or not. Don’t obey it, get wrong answers.
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.
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. You’re not nearly as smart as you seem to think you are.
It is though. Here’s a link to buy a printed copy:
BWAHAHAHAHAHAHA! They print it out when someone places an order! 😂
You keep mentioning textbooks but haven’t actually shown any that support you. I have
No you haven’t. You’ve shown 2 websites, both updated by random people.
I’ll trust the PhD teaching a university course on the subject
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.
over the nobody on the internet
Don’t know who you’re referring to. I’m a high school Maths teacher, hence the dozens of textbooks on the topic.
Talking about yourself in the third person is weird
Proves I’m not weird then doesn’t it.
Even your nonsense about a silent “+”
You call what’s in textbooks nonsense? That explains a lot! 😂
is really just leaving off the leading 0 in the equation 0+2
And yet the textbook says nothing of the kind. If I had 2+3, which is really +2+3 (see above textbook), do I, according to you, have to write 0+2+0+3? Enquiring minds want to know. And do I have to put another plus in front of the zero, as per the textbook, +0+2+0+3
Because addition is a binary operator
No it isn’t 😂
Only the ones that operate on two inputs.
Now you’re getting it. Multiply and divide take 2 inputs, add and subtract take 1.
Some examples of unary operators are factorial, absolute value, and trig functions.
Actually none of those are operators. The first 2 are grouping symbols (like brackets, exponents, and vinculums), the last is a function (it was right there in the name). The only unary operators are plus and minus.
I can’t keep trying to explain the same thing to you
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 their credentials beat “claims to be a high school math teacher but had trouble counting to 2” 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. 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 though. 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. Keep laughing though, you just look dumber every time.
Again, it’s not me who’s wrong.
Again, according to literally everyone, 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. And as much as I enjoy dunking on dipshits, I’ve got other things to do.
Welcome to it’s not a textbook (and it wasn’t about order of operations anyway).
We have this thing called the internet so people can share information without killing trees
We also have this thing called textbooks, that schools order so that Maths classes don’t have to be held in computer labs.
It’s the resource material for a college course
And the college doesn’t teach order of operations.
That’s like the definition of a text book
by someone who can’t back up their statements with actual textbooks.
One is a PhD teaching a college course on the subject
Yep, exactly what I said - a random person as far as order of operations is concerned, since he teaches Set Theory and not order of operations.
the other is Wolfram
Yeah, their programmers didn’t know The Distributive Law either.
I’m willing to bet their credentials beat “claims to be a high school math teacher” pretty soundly
Happy to take that bet. Guarantee you neither of them has studied order of operations since they were in high school.
This portion of the discussion wasn’t about order of operations
Yes it is. I said that order of operations dictates that you have to solve binary operators before unary operators, then you started trying to argue about unary operators.
it was about the number of inputs an operator (+, and - in this case) has
Yep, the ones with more inputs, binary operators, have to be solved first.
Try to keep up
Says person who’s forgotten why we were talking about it to begin with! 😂
At least your repeated use of the plural maths means you’re not anywhere near my kids.
Well that outs yourself as living in a country which has fallen behind the rest of the world in Maths, where high school teachers don’t even have to have Maths qualifications to teach Maths.
when those symbols are being used as a “sign of the quality” of the number it’s referring to
which is always. As usual, the comprehension issue is at your end.
not when it’s being used to indicate an operation like addition or subtraction
Yes it is 😂
Hopefully that clears it up
That you still have comprehension issues? I knew that already
This is ignoring the fact that a random screen shot could be anything
The name of the book is in the top left. Not very observant either.
For all I know you wrote that yourself
You don’t care how much you embarrass yourself do you, given the name of the book is in the top left and anyone can find and download it. 😂
because the first “+” isn’t an operator
Yes it is! 😂
It’s, as your own picture says, a sign of the quality of 2
and a sign of the quality of the 3 too. There are 2 of them, one for each Term, since it’s a 1:1 relationship.
I would love to know how you get to a sum or difference with only one input.
You don’t. Both need 2 Terms with signs. In this case +2 and +3.
2 is the first, and 3 is the second
Yep, corresponding to the 2 plus signs, +2 and +3. 1 unary operator, 1 Term, 2 of each.
Two inputs for addition
2 jumps on the number line, starting from 0, +2, then +3, ends up at +5 on the number line. This is how it’s taught in elementary school.
Did you get it this time?
The real question is did you?
Was that too fast?
No, you just forgot one of the plus signs in your counting, the one we usually omit by convention if at the start of the expression (whereas we never omit a minus sign if it’s at the start of the expression).
You can go back and read it again if you need to
I’m not the one who doesn’t know how unary operators work. Try it again, this time not leaving out the first plus sign.
Fine, operation then
Nope, not an operation either.
The fact that you think “!” is the same thing as brackets
I see you don’t know how grouping symbols work either.
Maybe you’re just being weirdly pedantic about operator vs operation
Grouping symbols are neither.
Which would be a strange hill to die on since the original topic was operations
You were the one who incorrectly brought grouping symbols into it, not me.
I could keep providing sources
You haven’t provided any yet! 😂
I still don’t have the time to screen shot some random crap with no supporting evidence
Glad you finally admitted you have no supporting evidence. Bye then! 😂
