Fortunately, the rules necessary to resolve the equation in this post are extremely elementary, so none of what you're referencing has any bearing whatever.
There are exactly three things to consider in here to determine priority: parentheses, multiplication/division, and addition. The addition happens first due to the parentheses, and the remaining is evaluated left-to-right. The only correct answer here is 16.
All your deflection from your embarrassment at misreading a simple equation doesn't detract from this.
this would be like trying to tell a chemical engineer they didn't know what they were doing based on your understanding of the atom as a ball of protons with electrons wooshing round it like they were moons
very cute
unfortunately, if you give the expression
1 / 2xto anybody who knows what they're doing they'll interpret it as1 / (2x)because it would be absurd not tofor reference, that's why the calculator works like this. because it's a tool designed primarily for people who actually know what they're doing with numbers, so it works how they expect it to work
And there you've proven exactly what I've been saying all along. 2x works the way it does because there's a variable involved, and natural reading of that treats it as a single entity. There are no variables in the equation in the post, there are only definite numbers, parentheses, and simple mathematical operations. 8/2(2+2) is nothing more than 8/2×(2+2). There is nothing special about 2(..., this is not the equivalent of 2x.
a natural reading of
2(2+2)treats it as the sameyou're straight up just spouting contradictory nonsense now because you've realised your stance doesn't make any sense, and i am very much here for it
No, what I'm explaining to you is the facts behind what every calculator with any modicum of computing power will tell you, namely that 2(2+2) is identical to 2×(2+2).
ah yes it's the computing power that's at issue here
Yeah, kind of. The crappier calculator is the one generating the incorrect answer. Any calculator with any real level of oomph behind it can parse this correctly to get the correct answer, 16.

The good calculator is the one using the processing power of the phone to handle the programming necessary to correctly interpret the order of operations and arrive at the correct answer, whereas the bad calculator - despite having no ads - is a cheap piece of trash unable to contain the necessary computational logic to arrive at the correct answer.
try again
No need. The fact that you're incapable of comprehending it at this point indicates that any further attempts to explain it to you are equally likely to fall on deaf ears.
you're boring now ;(
And you've long since given up trying to defend your incorrect position, so I can only assume that you're childishly continuing in an attempt to get the last word. That's fine, go right ahead and have the last word, I won't reply further since it's that important to you.
😘
Which would be the app written by the programmer who didn't check his Maths was correct, as opposed to the calculator made by a company who, you know, makes calculators.
Just like 2(2+2) is also a single Term.
Pronumerals literally stand in for numerals, and work exactly the same way. There is nothing special about choosing a pronumeral to represent a numeral.
They're completely different actually. 2(2+2) is a single term in the denominator, (2+2) - which you separated from the 2 with an x - is a now 3rd term which is now in the numerator, having been separated from the 2 which is in the denominator.
So what's it equal to when x=2+2?
