Comment on I dunno
SmartmanApps@programming.dev 1 day agoYes, the math textbook says exactly what I said, that it’s a multiplication
Nope, they say it’s Brackets…
5(36)=(5x36) <== Brackets
bc=(3x4) <== Brackets
There’s no mention of it being a separate operation taking precedence
It’s part of the Brackets step. I have no idea what “separate operation” you’re talking about
The parentheses in your example are added for clarity
Nope. They are there because The Distributive Law requires them. “those who study algebra are required to make their calculations conform to these laws”.
Whether you give priority to juxtapositions is a
A literal Law of Maths. See textbook.
the consensus being to just use parenthesis around when writing in a single line to avoid confusion.
No it isn’t. You won’t find any Maths textbook that says that.
However, there is no distribution step taking precedence
There is the Brackets step, including Distribution, taking precedence, as per Maths textbooks 🙄
as you mentioned
As the textbooks mention
the whole debate centers around whether the writer was too lazy to add parenthesis
The only debate is by people like you ignoring what is taught in Maths textbooks.

Nowhere in your “proof” screenshots does it say anything about distribution being part of the brackets step. Distribution is a method that can help solve equations, but it isn’t required. If you have 2(3+5) you’re free to solve it as 2*3+2*5 or as 2*8, whichever is easiest. That is because juxtaposition means multiplication and nothing else.
Math textbooks almost universally will either use clear brackets or simply write divisions in 2 lines, which avoids the confusion altogether.

Which step is first? Brackets. What do they do first in 5(36)/9? The Brackets.
What does the other textbook do with bc? Puts it in Brackets. Which step is fist in order of operations? Brackets 🙄 What do they end that page with? “those who study algebra are required to make their calculations conform to these laws”. You seriously need to work on your comprehension that I need to explicitly spell out to you what the textbooks say
The Property is. The Law is a rule which literally must be obeyed, as per Maths textbooks 🙄
Yes it is! That’s why it’s a Law 😂
Nope, neither
1/2(3+5)=1/(6+10)
1/2x3+2x5=3/2+10 WRONG ANSWER
1/2x8=8/2=4 WRONG ANSWER
Welcome to why it must be in brackets, as per Maths textbooks 🙄
says person who can’t cite any Maths textbook that says that. Nope! It means it’s a Term/Product, the result of a Multiplication (or Factorisation), and nothing else…

Note that it never used the word Multiplication at all in that definition 🙄
or an obelus or slash on one line

Only people who don’t remember the rules of Maths are confused about it. Students have no trouble with it.

Here is math for kids www.mathsisfun.com/…/distributive-law.html
Distributive law means you are allowed to distribute, not that you must distribute. I’m so sorry for the amount of effort you’re futilely putting into this lmao. Nowhere in all your sources and screenshots is it stated you must distribute, and thus the entire argument breaks down.

Yep, that’s about The Distributive Property too 🙄 Every time Multiplication gets mentioned, you know they’re talking about the Property, since the Law has no multiplication in it, but The Distributive Property of Multiplication over Addition does
No, the Property does. The Law tells you that you literally must Distribute.
Because The Law says that, hence why it’s a Law 🙄
says someone who can’t even tell the difference between the Property and the Law 😂
Yes it does liar
Not for people who know how to read 😂
