Division and multiplication are equal in the order of operations
I didn't say they weren't. I said...
Doing division before brackets goes against the order of operations rules
You did 8/2x4, which is the same as (8/2)(2+2), which isn't the same as 8/2(2+2)=8/2(4)=8/(2x4).
Not sure how you came up with that conclusion. I never said anything about it being "just a blog post".
You said...
I don’t understand how the author of the post lands on “there is no good or bad way, they are all valid”
And I'm pointing out he arrived at that by ignoring what's taught in high school, which is where it's taught (not in academia). It's like saying "It's ambiguous if there's such a thing as rain" if you present weather evidence which has omitted every single rainy day that has happened. i.e. cherry-picking. Every single blog which says it's ambiguous has done the exact same thing. You can find what actually is taught in high school here
It is a funny little bit of notational ambiguity
It's not ambiguous - it's The Distributive Law. You got the correct answer, you just forgot what the rule is called (as opposed to people who forget the rule altogether).
Semi-related: something in me wants to read that as 6 / (2*3)
100% related actually, since that's the actual next line of working out. i.e. you cannot remove brackets unless there is only 1 term left inside, a mistake which those who have prematurely removed brackets have made and ended up with the wrong answer (because it flips the 3 from being in the denominator to being in the numerator).
I believe you meant x(y+z)=xy+xz.
Actually it should be x(y+z)=(xy+xz), as that's exactly where a lot of people go wrong. They go from 6/2(1+2) to 6/2x3, instead of to 6/(2x3), and thus end up with the wrong answer (cos that flipped the 3 from being in the denominator to being in the numerator. i.e. instead of dividing by 3 they are now multiplying by 3, all because they removed brackets prematurely).
That'd be good, but what I've found so far here is a whole bunch of people who don't like being told the actual facts of the matter! 😂
you provided so many great references
Except for any actual Maths textbooks. Try this instead.
That's really cool!
why do you think most business are already writing a separate Android app
I don't think that. I know some businesses who are still writing separate apps, instead of switching to cross-platform. You'll have to ask them why they're doing that. It frustrates me no end when platform-specific bugs come up because they're running different code on each platform, each written by different people.
the fact that people interact by touch rather than with a mouse and keyboard
...makes no difference at all. Whether a user has touched a button, clicked on it, or tabbed to it and pressed enter, the same Button.Clicked event gets triggered.
Ah ok. Hopefully there'll be another update soon then that might fix it (a programmer's most feared words - "update available" ;-) ). Thanks! And also thanks for confirming not just dotnet.social that this is happenning on.
The opposite of div is to multiply. The opposite of frac is to invert the fraction.
