  • Chain calculators are the subject

    No they’re not…

    And when that was proven wrong the goalposts got moved to chain calculators, because neither of you are man enough to admit you were wrong 🙄

    we are talking about chain calculators

    You have been since you were proven wrong about all basic, non-scientific, non-graphing calculators 🙄

    they’re the ones with only an accumulator

    Which isn’t all basic, non-scientific, non-graphing calculators 🙄

    the topic is calculators where 2+3*4 gets 20

    No. the topic was…

    which was proven wrong

    say the Sinclair Executive could totes mcgoats do (a+b)c+(d+e)f

    It can’t, because no brackets keys, the calculator does have a stack, as per the manual in which (2+3)x4=20 and 2+3x4=14

    Do you understand there are calculators that can’t?

    Do you understand the claim was that none of them can?

    do you actually believe chain calculators are a thing that exists

    It’s right there in the manual! 🤣🤣🤣


  • Yes, this textbook says a(bc)2 works differently from how you say it works

    No it doesn’t 🤣🤣🤣 I have said the whole time that a(bc)²=ab²c², which is exactly what this textbook does 🙄 a(b+c) is different to a(bc)², duuuhhh 🙄

    You don’t have an answer for that because you’re a fraud

    says person who can’t quote any part saying it works differently to how I said, and in fact quoted a part showing it works exactly how I said 🤣🤣🤣

    If you want textbooks that also disprove how you pretend a(b+c)n works

    been telling you the whole time it’s irrelevent to a(b+c) which has no exponent Mr. False Equivalence 🙄


  • That just displays the accumulator

    Which is a single value stack, 🙄 but this calculator does indeed have a multivalue stack, so as to be able to do a+bxc, where it will put a+ on the stack (that’s two values, a and +), calculate bxc, then pop the stack and do the addition. If you instead want to do (a+b)xc, you have to press equals after a+b so that it will get evaluated before the Multiplication, because it doesn’t have Brackets keys 🙄

    (a+b)c+(d+e)f “cannot be done as a simple calculation, it must be split into two parts.” Because there’s no stack

    No, that’s because it doesn’t have any brackets keys 🙄 You can get away with one set of brackets as per the method shown, but you can’t do that with multiple brackets. You really have no idea how Maths or calculators work! 🤣🤣🤣

    Here’s an online emulator for the Sinclair Cambridge, the upgraded scientific model

    We’ve already established that’s a chain calculator Mr. needs remedial reading classes 🙄






  • this linked comment

    Dude, why didn’t you say before? In the first place you were talking about the link, and I told you that the link took me to the index, and it took until now for you to say it was never in the link. 🙄 You just kept posting the same link to a comment and not to the textbook 🙄

    PDF page 27

    BWAHAHAHAHAHA! Did you even read it??? 🤣🤣🤣

    In other words, a(b+c)=(ab+ac), like I have been saying all along 🤣🤣🤣

    Also says this…

    says they are applying The Distributive Property, NOT The Distributive LAW 🤣🤣🤣

    Now, that was all on Page 27, which did not include the example you gave. Where is it? On Page 28, talk about not being able to read BWAHAHAHAHAHAHA! 🤣🤣🤣

    And, same applies - they’re using The Distributive Property, NOT The Distributive Law 🤣🤣🤣

    showing an equation that does not obey your made-up bullshit

    That’s because I don’t have any made-up bullshit - only you do! 🤣🤣🤣 You need to learn to read dude. Quite clearly states they are using the Distributive Property in the process of collecting like Terms, which isn’t using The Distributive Law to Expand Brackets. You need some remedial reading classes dude 🙄

    In a maths textbook

    Yep, and does not contradict anything that I have said 🤣🤣🤣

    This would be easier if you could read

    says person who gave the wrong page number, about the wrong rule, in the wrong topic 🤣🤣🤣



  • Follow this fully intentional link,

    Which you are admitting is fully intentional NOT the link for this…

    I’ll take that as an admission then that it in fact does not prove me wrong, as you first claimed, since, despite repeated requests, you have been unable to tell me where it supposedly proves me wrong, which of course I knew would be the case to begin with when you failed to tell me where it supposedly proves me wrong 😂

    learn some goddamn reading comprehension.

    says person still posting the wrong link 🙄


  • The answer to 2 2 3 + / does not involve brackets.

    (2+3)/2

    Don’t you know all equations are secretly RPN, in the background?

    No they aren’t liar. They are broken down into binary trees. I teach Computer Science as well dude.

    Here’s the binary tree for 2 2 3 + /

    Here’s the binary tree for (2+3)/2

    Oh look! it’s the exact same tree! Who woulda thought. Oh yeah, me - I’ve only been telling you that the whole damn time 😂

    There’s only a stack,

    Yep, that’s where things in brackets get put alright - see binary tree above😂

    the rules for a stack are that brackets do not work

    Except I just proved they do 😂


  • Have to reply to your other post here, because you hit the maximum comment depth with your rubbish.

    I thought they were called “products” not “multiplications”

    That’s right, as per Page 36 of Modern Algebra, published in 1965, as opposed to Advanced Algebra, published in 1912., but if you think we still call it “Multiplication” you’re more than welcome to find a modern textbook which calls it that, instead of relying on a 113 year old textbook 🙄

    If you can find an explicit textbook example where writing a(b)²

    What did you not understand about textbooks write ab² if they meant (axb²)?

    that’s another way you can prove your good faith

    I already proved it with all my other textbook references, which you keep ignoring 🙄

    the exponent could be anything other than 1

    In other words, you refuse to believe the rule that I have already quoted multiple times, because it proves you are wrong about this meme, and so trying to derail the argument, still, with your false equivalence argument, speaking of lacking good faith 🙄

    Likewise, if you can find any explicit textbook example which specifically mentions an “exception” to the distributive law

    There aren’t any exceptions. I’m not sure why you’re having trouble with that. You want me to find evidence of something I have said all along doesn’t exist 😂

    I’m not saying that such an explicit example is the only way to demonstrate your claim

    says person who to date has refused to accept what any textbook has said about it 🙄

    I’m just trying to give you more opportunities to prove that you’re not just a troll

    Since when do trolls post Maths textbooks backing them up? 🤣🤣🤣

    that it’s possible to have a productive discussion.

    says person who has rejected literally every Maths textbook I’ve posted. 🙄

    You insist you’re talking about mathematical rules that cannot be violated

    as per Maths textbooks 🙄

    so it should be no problem to find an explicit mention of them

    …and I already posted many of them, but for some reason you find them unacceptable (that reason being that they prove you are wrong 😂 )

    you should remember that you are saying that the practice of calculators, mathematical tools, programming languages and mathematical software are all wrong

    Nope, liar. All calculators except for Texas Instruments and e-calcs are correct - certainly all my calculators are correct (as can be seen in the video in the thread). Same thread shows the reason that programmers are almost all wrong - they don’t even all get it wrong in the same way - everyone gets it wrong in different ways, which debunks the whole idea of them following any rules 😂

    that my interpretation of your own textbooks is wrong

    Which you would’ve found out for yourself, had you read more than 2 sentences out of them. 🙄 Welcome to what happens when you only read the scaffolding part of a lesson, and not the new content part of the lesson 🙄

    if you show no ability to admit error

    says person who has failed to admit their error about the calculators. 🙄For me to do so would require me having made an error to begin with, which I haven’t, which is why you’ve been unable to say where I’ve made an error 🙄

    to admit that disagreement from competing authorities casts doubt on your claims

    There isn’t any disagreement from competing authorities, and yet you still refuse to admit you’re wrong 🙄

    to evince your controversial claims with explicit examples that are not subject to interpretational contortions,

    says the only person who has made such contortions, such as “means” means “equals” 🙄

    the likelihood is that you’re not willing to ever see truth

    You you mean, as evidenced by the fact that you had already dismissed me as being good faith in your above post before I had even seen THIS post - something, something, judge, jury, and executioner 🙄

    there’s no point arguing with such a person

    I’m not arguing with you - I’m debunking your rubbish claims lest any reader fall prey to them

    sorry for making multiple replies on the same point

    Which at the end of it all you had still failed to make a point.

    As my own show of good faith, I do see that one of your textbooks (Chrystal) has the convention that a number “carries with it” a + or -, which is suppressed in the case of a term-initial positive number

    No, a show of good faith by you would be 1. accepting that axb and ab are different, as per the page you reference above, which I’ll come back to in a tick, 2. accepting The Distributive Law, a(b+c)=(ab+ac), is a thing found in many Maths textbooks (all of which you ignored), otherwise all you have conceded was yet another side-quest on your part because you refuse to concede anything which is actually relevant

    So, you started this post with referencing Page 6 of Advanced Algebra (as proven by you quoting the bit about “Multiplication”, which explicitly shows that bxc and bc ARE NOT THE SAME THING, and yet here you are still not acknowledging this fact.

    a÷bxc=12÷3x4=16, a÷bc=12÷(3x4)=1

    I’ll explain why I think this is a bad convention

    It’s not a convention, it’s a rule 🙄

    why the formal first-order language of arithmetic doesn’t have this convention

    No-one cares 🙄 Most people don’t go to university and learn niche rules, everyone goes to high school and learns the general rules

    You failed to demonstrate any good faith

    says the person who actually demonstrated no good faith 🙄 and was unable to back up anything they said with a textbook

    so this is the end of this conversation

    Don’t let the door hit you on the way out

    Your reply reveals that you even understand that you were wrong

    Nope!

    “it’s designed that way”

    Yep, that shows I was correct about “simple” calculators, whereas chain calculators were designed that way, but that was used as moving goalposts by the person claiming this applied to “simple” calculators, which was disproven by the manual showing that it did indeed have a stack and obey the order of operations rules, hence the goalposts got moved, again 🙄

    the language changed

    You think it doesn’t change?? BWAHAHAHAHAHA 🤣🤣🤣 But sure, Mr. I’m (not) showing good faith, go ahead and show us a modern textbook which calls Products “Multiplication”. I’ll wait. 😂 Oh wait. you said the conversation was over. Too bad you can’t prove your point then… again

    but are so prideful,

    Correct is the word you’re looking for

    so averse to ceding ground,

    says person who has failed to come up with a single valid point that I could therefore cede to 🙄

    that you just… can’t… say it!

    says person who has failed to admit they are wrong about things they have been proven wrong about 🙄

    The children you really ought to stop teaching are more mature than this.

    They’re more mature than you yes. They have no problem at all with The Distributive Law and why it exists, and can see their calculators know this also.

    You’re an embarrassment to the profession.

    says the actual embarrassment who can’t back up anything they say with any Maths textbook 🙄


  • Man, this whole post has been embarrassing for you

    Nope. I’m the only one who has backed up what they’ve said with Maths textbooks 🙄

    I can’t help but notice youve once again failed to address prefix and postfix notations.

    What is it that you want addressed?

    And that you’ve not actually made any argument other than “nuh uh”

    Backed up by Maths textbooks 🙄

    We can all tell you’re not a maths teacher

    Says person who actually isn’t a Maths teacher, hence no textbooks 😂



  • A “teacher” who doesn’t know that all lessons are simplifications that get corrected at a higher level,

    As opposed to a Maths teacher who knows there are no corrections made at a higher level. Go ahead and look for a Maths textbook which includes one of these mysterious “corrections” that you refer to - I’ll wait 😂

    refers to children’s textbook as an infallible source of college level information

    A high school Maths textbook most certainly is an infallible source of “college level” information, given it contains the exact same rules 😂

    A “teacher” incapable of differentiating between rules of a convention and the laws of mathematics

    Well, that’s you! 😂 The one who quoted Wikipedia and not a Maths textbook 😂

    A “teacher” incapable of looking up information on notations of their own specialization

    You again 😂 Wikipedia isn’t a Maths textbook





  • when talking about four-function calculators that do not have a stack

    Chain calculators, as the second one said in the manual

    Insisting ‘but it does have a stack!’ is the problem

    The first one does have a stack. 🙄 You refusing to see it is the problem

    And read usernames

    Your mind’s been bleached - explains a lot 😂

    The Sinclair Executive in that manual does not have an equals key

    It has a += key. If the next keypress is a number it’s interpreted as +, if the next key pressed isn’t a number, like the x button, it’s interpeted as equals Duuuuhhh It even explicitly points out to you that the result of that keypress is (a+b) 🙄

    What the fuck are you talking about?

    The example in the manual. What are you talking about? 😂


  • Wikipedia

    isn’t a Maths textbook 🙄 far out, did you learn English from Wikipedia too? You sure seem to have trouble understanding the words Maths textbook

    You don’t trust Wikipedia?

    The site that you just quoted which is proven wrong by Maths textbooks, THAT Wikipedia?? 🤣🤣🤣

    you’ve yet to explain why notations like prefix and postfix dont need these “rules”.

    Umm, they do need the rules! 😂

    how could they only apply to certain notations?

    They don’t, they apply to all notations 🙄
