Whatever makes you feel better about your ignorance.
Says person who proved themselves wrong, and is now withdrawing from the conversation to hide their ignorance 😂
One day you’ll look back at this and think “damn, I really was an idiot back then!”
Says person who has run out of mental gymnastics that can be applied. I'll take that as an admission of being wrong then
Parentheses means evaluating the things inside the parentheses you nimrod
Only if you're still in Elementary school. How old are you anyway? Here's a high school Algebra book, you know, after students have been taught The Distributive Law...
I’m falling for the troll here
Just as well for you I've provided all the necessary evidence to prove them wrong then
I’m honestly disappointed that you just downvoted and left
BWAHAHAHAHAHA! I DIDN'T leave, quite demonstrably.
Challenging your beliefs with contrary ideas is the only way to improve them and understand the world in a more comprehensive and accurate way
So how come you won't then?
I should clarify that I haven’t responded to your “points” because there is nothing worth responding to
In other words, you have been proven wrong by them
Your arguments can all be debunked by reading https://en.wikipedia.org/wiki/Order_of_operations
Wikipedia can be comprehensively debunked by MATHS TEXTBOOKS - you know, those things you refuse to look at because they prove you are wrong 😂
I didn’t bother doing it myself.
So in other words, Wikipedia is all you had, and, having been disproven by Maths textbooks, you've got nothing
I will be blocking you
An admission of defeat then
I feel that the deleted post is in itself a very good final word to this disappointment of a “conversation”
Feel free to unblock me when you're ready to take your own advice
if it is not entirely accurate
Just like all your other posts then
Goodbye
Don't let the door hit you on the way out
Bro directly after what you underlined it says “if you want to remove the brackets”
Yep, that's right, and removing brackets is the first step in order of operations 😂
Selective reading much?
By you apparently.
“If” means optional
So... you're telling me that the "B" step in BEDMAS, and the "P" step in PEMDAS, is optional? I don't have to remove Brackets?? 😂 Better go back to school dude
You are free to solve what’s inside the brackets first, before multiplying it with what’s outside
Yep, but inside the brackets, as per the text you can see in the screenshot 😂
5(8-5)=(5x8-5x5)=(40-25)=15
5(8-5)=5(3)=(5x3)=15 <== Multiplication inside the Brackets, as per The Distributive Law
same answer both ways 😂
the link I posted is literally titled “distributive law”, not property
But has a multiply sign in it, thus proving it is the Property that they are talking about - The Distributive Property of Multiplication over Addition to call it by it's full name
You realize a law can have conditions, right?
You realise it literally must be obeyed, right? The condition that The Distributive Law has, is "A number or letter next to a Bracket", direct quote from the textbook, hence a(b+c)=(ab+ac), and not ax(b+c) since the a is not next to the bracket in that case
it’s actually a kind of “mental exercise” for me
Yep, mental gymnastics left, right, and centre 😂
This guy thinks 3(2+1) gets the wrong answer if you do 3(3)
No I don't, liar. Hilarious that now you're having to resort to making things up 😂
instead of 32+31
Which can definitely give wrong answers
1/3(2+1)=1/(6+3)=(1/9)
1/3(3)=1/(3x3)=(1/9) same answer
1/3x2+3x1=(3/2)+3 Oops! WRONG ANSWER 😂
proceed knowing it’s all you’re going to get
All you're going to get from me is facts, correct, as opposed to you who can't come up with any facts! 😂
And what do you do with the number inside the when you want to get rid of it?
You literally must distribute the coefficient before you can do anything with what is inside to remove Brackets, as per The Distributive Law, a(b+c)=(ab+ac), now you can work on getting rid of what is inside.
Yes it is
You can say that as much as you want and you'll still be just as wrong. Noted that, yet again, you are unable to cite any Maths textbooks that agree with you
If you understand what is multiplication and what is addition
Again, the mnemonics are for people who don't understand, which would be people like you! 😂
What’s the result of 2/2 and what’s the result of 2*½
What's the result of 2+2? What's the result of 1+3? Are 2+2 and 1+3 the same? No! 😂 2 apples + 2 oranges = 4 pieces of fruit. 3 apples and 1 orange = 4 pieces of fruit. Is 2 apples and 2 oranges the same as 3 apples and 1 orange? 😂 Anything else you want to embarrass yourself about not understanding?
Explain how is that relevant to the discussion
You're the one who brought it into the conversation - you tell me! 😂
where brackets are only used for readability sake
You'll find most people find that less readable. Welcome to why textbooks never use them
they’re not changing the results in any way
Just making it less readable.
Well… yes, because we’re not talking about the history
You are when you start dragging brackets into something that never used brackets for hundreds of years
we’re talking about the current rules
which haven't changed at all in all that time 😂 2-3 has never and still does not require brackets, same as when Arithmetic was first written.
This whole thread stemmed from the fact that some people were taught PEMDAS while others where taught PEDMAS.
and everyone was taught that the order of DM/MD does not matter. If it did then one of them would not exist
Are you suggesting that the order of operations depends on your maths teacher?
No! You might want to work on your comprehension as well 😂
Wow, let me be the first to welcome you to the Internet!
Been here longer than you probably, and know full well what you said is a lie 😂
Now find one that actually talks about that
Already posted a screenshot of one. You really need to work on your comprehension
the addition of similar monomials, which is a different thing altogether
Set all the pronumerals to 1, and guess what you have - the exact same thing 😂 I see you don't understand how pronumerals work either
BTW you still have not cited any textbook whatsoever that agrees with anything that you have said, in case you needed that reminder 😂
instead just read the part you posted, but slower.
says person who doesn't understand that pronumerals can equal 1. 🙄
the arithmetical difference between the total of the positive and the total of the negative coefficients,
Yep, 1a-2a+3a-4a=a((1+3)-(2+4)). Now set a=1 and guess what you have? 😂
giving it the sign of the numerically greater total, and annexing it to the common literal part
You telling me you don't understand what that means? +4-2=+2. +2-4=-2. Not complicated
Which actually
proves you're wrong 😂
Addition is NOT first
You know the textbook just literally told you it is, right?? 😂
unless it’s the first on the right
It's first regardless of where it is. Did the textbook says it depends on where it is? No 😂
Again, let me extend a warm welcome on behalf of everyone on the Internet
Where nearly half of adults have forgotten the rules of Maths, and everyone else knows there is no problem 😂
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
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!" 😂
The rules are socially agreed upon
Nope! Universal laws.
They are not a mathematical truth.
Yes they are! 😂
There is nothing about the order of multiple different operators in the definition of the operators themselves
That's exactly where it is. 2x3 is defined as 2+2+2, therefore if you don't do Multiplication before Addition you get wrong answers
you can order those however you like.
No you can't! 😂 2+3x4=5x4=20, Oops! WRONG ANSWER 😂
All that matters is just what calculation it is that you’re after
And if you want the right answer then you have to obey the order of operations rules
other way around dude, as proven by screenshots
So you want to keep it here, because the other is full of screenshots proving you wrong and you want to ignore them?? 🤣🤣🤣
