@julia_doubleday I'll say to you again, come to Mastodon. You will find more support for your work there than here.

[💡 Smartman Apps 📱 (@[email protected]) @SmartmanApps]

@julia_doubleday Come join us on Mastodon (I only came here to say that - I read your posts from there usually, would much rather you were there in the first place :-) )

Come to Mastodon please. A world free of billionaire owners. :-)

@knightlight4 @JangotheFox @Lyssa_Ishida @Jun_on_Fire "ask google" - ask Google about African countries that start with K and see how you go. 😂

"most people agree" - adults who've forgotten the rules isn't "most people".

"has to be clarified more to 6/(2(1+2))" - no it doesn't. It already means that, per a(b+c)=(ab+ac)

@knightlight4 @JangotheFox @Lyssa_Ishida @Jun_on_Fire Let me help you out with a whole bunch of textbook references - both old AND NEW 🤣

@knightlight4 @JangotheFox @Lyssa_Ishida @Jun_on_Fire Did you actually READ the letter he refers to? It states quite clearly "all multiplication first", thus 6/2x3=6/6=1. 🤣 Also that rule was never adopted anyway. We still have the same rules as 100 years ago. Maybe in future you should check references when they're given. 🤣

@knightlight4 @JangotheFox @Lyssa_Ishida @Jun_on_Fire "that is only if you're talking algebra" - no it isn't.

"it would be 6/(2(1+2))" - which is EXACTLY the same as 6/2(1+2). a(b+c) is the standard form of a factorised term. Look up literally any Maths textbook chapter on Factorising - it's written the same way in ALL of them.

@knightlight4 @JangotheFox @Lyssa_Ishida @Jun_on_Fire "the 2 doesnt magically go into the bracket" - no, it goes in via The Distributive Law - a(b+c)=(ab+ac) - that's precisely what the notation was invented for, to indicate a Factorised Term. ab+ac=a(b+c). 6/2(1+2)=6/(2+4)=6/6=1.

@reddie1907 @triquetra0 @Sakuraaa_XIV @Jun_on_Fire You think Maths textbooks are wrong?? 😂 BTW I teach this topic.

[💡 Smartman Apps 📱 (@[email protected]) @SmartmanApps]

@Kryzalydd @FreestarXIV_kjk @Jun_on_Fire If you read it, it quite clearly states "a NUMBER or letter NEXT TO A BRACKET...". I see where the first 2 is, do you?

@Ryth_deathless_ @ValleyHipparion @Jun_on_Fire Maths teachers (and students) are getting it wrong? 😂 See Modern Algebra : Structure and Method, Book 1 by Dolciani, Mary P; Berman, Simon L; Freilich, Julius, page 282, questions 15 and 16, answers on page 577. Available on the Internet Archive

@JangotheFox @Lyssa_Ishida @Jun_on_Fire "the brackets disappear after adding up 1 and 2" - no they don't.

"6/2*3" - no, it's 6/(2x3). You can't remove brackets unless there is only 1 term left inside. 2x3 is 2 terms. You just broke up the factorised Term and flipped the 3 out of the denominator into the numerator.

Hey @doughendrie just letting you know I just sent a DM, in case you need to check your message requests to see it. Related to possible article if you're interested in writing it.

@alexwlchan "This numerical expression is ambiguous" - no, it isn't

"There are two interpretations" - only 1 is correct (literally! 😂)

"We need more information" - https://t.co/DJU3dh3OhG

@Mirasifm @eorzeandog @Jun_on_Fire So you just proved yourself wrong then 😂😂😂

[💡 Smartman Apps 📱 (@[email protected]) @SmartmanApps]

@Mirasifm @eorzeandog @Jun_on_Fire How do you divide by a fraction without it? I'll wait.

[💡 Smartman Apps 📱 (@[email protected]) @SmartmanApps]

@Mirasifm @eorzeandog @Jun_on_Fire Got nothing to do with if it's plus minus multiply or divide - it's an operator, operators separate terms.

[💡 Smartman Apps 📱 (@[email protected]) @SmartmanApps]

@Mirasifm @eorzeandog @Jun_on_Fire "hasn't been written as a fraction to make it ambiguous"
And yet it isn't ambiguous.

"You're so close to realising the issue"
I already know what the issue is - it's people who have forgotten their High School Maths rules. Bye now

@Mirasifm @eorzeandog @Jun_on_Fire Yes, there is, and yet this HASN'T been written as a fraction.
