Comment on I dunno
SmartmanApps@programming.dev 2 days agoLmao citing yourself
Nope! I cite Maths textbooks here, here, here, here, here, here, here, a calculator here, need I go on? 🙄 There’s plenty more of them
assuming you’re correct and smarter than everyone who programs solvers,
That’s hilarious that you think random programmers know more about Maths than a Maths professional 😂
even those who are known to be respectable and used extensively in academia
As I already stated, everyone knows the complete opposite of that about them. It’s hilarious that you’re trying to prop up places that give both right and wrong answers to the exact same expression as somehow being respectable. 😂 And you’ll see at the end of that thread - if you decide to read it this time - the poof that academia does not use it (because they know it spits out random answers)
Nothing’s been established cause you’ve cited sources that don’t support your argument
BWAHAHAHAAH! Like?? 😂
repeating them again and again won’t make it different.
That’s right, the Maths textbooks are still as correct about it as the first time I cited them.
continuing this is useless
Well it is when you don’t bother reading the links, which you’ve just proven is the case

I’ve read everything you’ve posted, but the problem is you’re interpreting the texts in such a way that they support your flawed argument, conveniently ignoring what they’re actually saying, such as “if” statements.
Even this textbook that you yourself posted goes against what you’re saying if you just bother to look at it outside of your tunnel vision: Image
Notice something?

You’ve read every textbook, and looked at the calculator answer? Yeah nah, you clearly haven’t.
Says person who can’t come up with any textbooks that support their argument. 😂 BTW if you had looked at the calculator, you would’ve seen it does it exactly as I have described - 6/2(1+2)=6/2(3)=6/(2x3)=6/6=1, not, you know, 6/2(1+2)=3(3)=9, which is your flawed argument
Says person ignoring this “if” statement which says you literally must distribute if you want to remove the brackets.
Image
No it doesn’t! 😂
Yes, you ignored the Distribution in the last step 😂 I have no idea what you think is significant about the first 2 steps, other than you were trying to draw attention away from the Distribution in the last step
Image
Here’s another one (different authors) that does the same thing, which you would’ve seen if you had actually read all the textbooks I posted, but they explicitly spell out what they’re doing as they’re doing it…

Yep I have looked at all you’ve posted, I say you’re wrong because what you’ve posted says things that are true, but you’re reading them wrong. For example your last image clearly says a number next to a bracket means the content of the bracket must be multiplied with said number. Nowhere there does anybody speak of distribution taking precedence over other operations. In fact, nowhere in all sources I can find does it say so. Wonder why all screenshots you post use convoluted wording and wonder why you pop up everywhere arguing the same thing and keep getting downvoted? At some point you need to understand that if one old-ass calculator and selective reading of cherry picked passages is all the proof you have, when all modern calculators and algebra solvers go against you, maybe it’s time to reconsider.
Juxtaposition taking precedence over other multiplications I can understand and it’s an arguable point. Distribution being a mandatory step and taking precedence over even exponents is just silly and unfortunately wrong.
Also another thing: you’re a math teacher as you’ve said, and consistently ask if I think “random programmers” know more about algebra than you. What I say to that is I’ve met plenty of teachers who are wrong about things in their own fields, for one. And also, people defining the rules of all those algebra solvers aren’t the programmers, as you’d know if you looked a bit into product development. It’s domain experts, who also define tests and receive feedback on the software’s performance and errors. I’m sure (lol) you’ve sent feedback to them, and they probably looked at it and decided you’re wrong. As well all have.

says the person who is actually reading them wrong, who is unable to cite any example of me reading it wrong
the content of the bracket - you just quoted that yourself and still completely missed what that means 😂
Image
BRACKETS has precedence over everything 😂 So here we have an example of you reading it wrong
And can you find any source which says Multiplication takes precedence over Brackets? No. Another example of you reading it wrong
They don’t use “convoluted wording”! 🤣
“the contents OF THE BRACKETS should be multiplied”
“everything IN THE BRACKET should be multiplied by that number”
Yet another example of you reading it wrong 😂
The only person downvoting me is the person replying, whereas the others are getting downvoted by others as well 🙄
My brand new calculator gives the same answer! 😂 They all do now, except for Texas Instruments - the only one stubbornly still doing it wrongly
Sure, I’m “cherry picking” the sections of textbooks about Distribution. Do you want me to post something random about a different topic? 😂 BTW, noted that you haven’t come up with any textbooks that agree with you
And it is indeed proof.
Agree with me (except for Texas Instruments)
Written by programmers who have forgotten the rules of Maths, and as pointed out by many people in forums.
And yet, here you are not reconsidering 🙄
Because BRACKETS - ab=(axb) BY DEFINITION 😂
Image
And is also the exact same rule 🙄
There’s a reason it’s called The Distributive Law
BRACKETS taking precedence over Exponents is “silly”?? 🤣🤣🤣
BRACKETS taking precedence over Exponents is “unfortunately wrong”?? 🤣🤣🤣
You think they’re wrong you mean, person who is saying Brackets before Exponents is “wrong” 🤣🤣🤣
Yes they are! That’s why they give wrong answers 😂 I told one he was wrong and he went and fixed it, being the one who had programmed it that way 🙄
I know they are because I have spoken directly to them 😂 Maybe try asking some yourself, before making completely wrong statements
No it isn’t, as proven by personal experience. You know who uses domain experts? calculator manufacturers. 😂 They have considerably more riding on it being right or not.
You know there’s a whole bunch of programmers who don’t bother even defining tests to begin with, right??
Yep!
Except for the ones who did change it. The ones who claimed I was wrong, quoted Google - who have also been told they’re wrong by many people -and not Maths textbooks 🙄
says person who did nothing of the sort, and lied about such things as "all modern calculators " being against me (they aren’t, if you had actually tried some), Exponents having precedence over Brackets, etc.
