It adds them in the background, so that you don’t have to - if it didn’t it would return wrong answers - you not having to type them in doesn’t mean they aren’t getting added

I don’t think you understand mathematics above the 7th-grade level you brag about teaching. No bona fides will excuse how you’ve acted; you have to be better. On the internet nobody knows you’re a dog, and you act like a child cosplaying a teacher that students hate.

RPN does not have parentheses, any more than standard notation can have a stack. The concept does not exist. Yet both forms of equation are equally valid, but different - in the same way as peasant multiplication versus new-math multiplication. I’m not saying this for your sake because you’re a broken robot. But since you’re spamming everyone in this two-week-old thread, some of them are going to scroll through wondering ‘is this schmuck for real?,’ and they deserve to know exactly how small-minded and stubborn you are.

You’re basically out here demanding that multiplication can only be done in the peasant method, so if someone’s explaining it without a list of doubled numbers, they ‘can’t admit they’re wrong.’ So you’re going to henpeck them one line at a time, ignoring the many ways they try to politely explain you’re being a pedantic troll, and pounding books that reflect knowledge as if they define knowledge, until they all give up trying to spoon-feed you your own visible failure to teach anyone anything. Nobody’s walking away from these interactions like ‘oh thanks, good to know, that’s perfectly clear now.’ It’s wall-to-wall ‘I don’t think you’re as smart as you think you are’ and ‘you’re really missing the point’ and ‘if it always gets the same answer then there’s no meaningful difference.’

Yet tour dogmatism is so blatant that you’re assigning Buddha nature to parentheses. Your philosophy cannot comprehend a math notation where you’re even merely overreaching, let alone mistaken - so parentheses flit into being, somewhere in a stack operation between two numbers at a time. 1 2 + 3 * is not an equation with parentheses. Order of operations is baked into the order of operands. The first time I explained this to you, you had never heard of it. Yet you immediately asserted you’d found something missed by all all other people, sites, and indeed ~~holy texts~~ maths books.

You are a crank. Trying to ‘no u’ about your absence of self-awareness does not work, because you didn’t predict me showing up to harass people with grade-school math while not listening. What you’re doing is troll behavior. If this is how you teach children, it’s enforced learning by rote, and their understanding of even basic mathematics is permanently hobbled by your smile-and-repeat-yourself rhetorical style.

I don’t think you understand mathematics above the 7th-grade level you brag about teaching

I don’t think you understand any of it, not even Year 7

No bona fides will excuse how you’ve acted; you have to be better

says person who refuses to look in Maths textbooks

RPN does not have parentheses

in the foreground. In the background it does or it would give wrong answers. You understand that apps can do things that you don’t see, right??

but different

Only the notation is different, the rules are the same

they deserve to know exactly how small-minded and stubborn you are

says the person who refuses to look in Maths textbooks 😂

as if they define knowledge

Textbooks do indeed define the notation and rules. 1+1=2 is defined as the notation to use to show that I had 1 thing and now I have 2 things

your own visible failure to teach anyone anything

says person ignoring all the people who actually did learn from me. That would be the people who are open to being wrong about how they thought it was done

Nobody’s walking away from these interactions like ‘oh thanks, good to know, that’s perfectly clear now.’

Yes they are! 😂

you’re assigning Buddha nature to parentheses

No, just literal textbook definition, which you refuse to look at 😂

1 2 + 3 * is not an equation with parentheses

So the app adds them in the background. Do you think apps don’t know how many “a” you’re talking about if you don’t write 1a? Guess what, it knows in the background that a=1a, and that the 1 in 1-2-3 is +1, etc. Not typing them in doesn’t mean they aren’t being added

The first time I explained this to you, you had never heard of it.

yet again you seem to have me confused with someone else. I have no idea what you’re talking about

You are a

Maths teacher

Trying to ‘no u’ about your absence of self-awareness does not work

says person who refuses to look in Maths textbooks

because you didn’t predict me

gaslighters gonna gaslight - there’s nothing unpredictable about that

What you’re doing is

teaching the rules of Maths

If this is how you teach children, it’s enforced learning by rote

No it isn’t, because they, having seen it also in the textbook, understand how it works

Image

their understanding of even basic mathematics is permanently

improved, because they don’t sit there going “Nah nah nah, nah nah nah, I’m not listening and not looking in the textbook!” 😂

  …
  
  You are functionally illiterate.
  
  RPN is not an “app.” RPN is a NOTATION. That’s what the N is. It is a completely different way of doing math! It works on paper! You troll! It is a syntax for performing calculations using a stack-based method. There are no fucking parentheses - anywhere. It has no need for that concepts. Operations use the top values on the stack.
  
  Do you know anything that’s not in a textbook for children?

    What do you think is behind the RPN calculators? A person?? 😂
    
    RPN is a NOTATION
    
    Yep, so is ALGEBRA 😂 The rules are independent of both
    
    That’s what the N is
    
    Yep, notation, not rules
    
    It is a completely different way of doing math!
    
    Nope! It’s only a different NOTATION - you just said that yourself! 😂
    
    It works on paper!
    
    So does Algebra - surprise, surprise, surprise 😂
    
    t is a syntax for performing calculations using a stack-based
    
    NOTATION
    
    There are no fucking parentheses - anywhere
    
    And I’m guessing you think there is no 1 anywhere in a+b, and there’s no + anywhere in 1-2
    
    Order of operations is implicit
    
    Which you could write explicitly with Brackets. 2 3 + 4 x = (2+3)x4
    
    completely different from the one thing you insist is both universal
    
    No it isn’t. 2 3 + 4 x gives the same answer as (2+3)x4, and 3 4 x 2 + gives the same answer as 2+3x4. Note that in the first example 2 3 + is effectively being bracketed, as otherwise you’d get a wrong answer by the order of operations rules
    
    Do you know anything that’s not in a textbook for children?
    
    Yep, everything in high school Maths textbooks 😂

    Distribution is “effectively” multiplication. Nothing you say, nothing you point to, could possibly change that, because they will always get the same answer, and if getting the right answer is all that makes two things the same, then shut the fuck up.
