That you’re still wrong?
About? You haven't pointed out anything that's wrong.
the problem is written poorly due to the obelus and thus is open to interpretation
Oh, you're one of those people. Good, maybe we can finally get an answer then (this was also talked about in the blog). What other interpretation of an obelus is possible other than division? People keep saying it's ambiguous, but no-one has ever said why (other than some stuff that makes no sense in the context, as explained in the blog)
The distributive property is sometimes called the distributive law of multiplication and division
Yes, and sometimes people call Koalas "Koala bears", but that doesn't mean they're bears. Now bearing that in mind, read again what Khan said - the page which is called "Distributive property explained", not "Distributive Law explained".
Wait till you hear that “i before e except after c” wasn’t true either
Wait till you hear that's not a rule of Maths.
It’s wild that you think 7th grade math overrules grad school math though
Umm, never said anything of the kind...
And...? Not sure what your point is, but the link is VERY badly worded...
- The Distributive Law and The Distributive Property aren't the same thing - he's applying The Distributive Law, but mistakenly calling it The Distributive Property (a lot of people make that mistake). The latter is merely a property in Maths (like the commutative property, the associative property, etc.), the former an actual rule of Maths The Distributive Law
- Applying the Distributive Law - i.e. expanding brackets/parentheses - is part of solving brackets. i.e. the first step in BEDMAS/PEMDAS. There's no "once you've used", you've already started!
- As I already said, this is taught in Year 7, so I'm not sure what your point is?
Even more ambiguous math notations
Except that isn't ambiguous either. See my reply to the original comment.
Geogebra has indeed found a good solution
Geogebra has done the same thing as Desmos, which is wrong. Desmos USED TO give correct answers, but then they changed it to automatically interpret / as a fraction, which is good, except when they did that it ALSO now interprets ÷ as a fraction, which is wrong. ½ is 1 term, 1÷2 is 2 terms (but Desmos now treats it as 1 term, which goes against the definition of terms)
What’s |a|b|c|?
The absolute value of a, times b, times the absolute value of c (which would be more naturally written as b|ac|). Unlike brackets, there's no such thing as nested absolute value. If you wanted it to read as the absolute value of (a times the absolute value of b times c), then that's EXACTLY the same answer as the absolute value of (a times b times c), which is why nested absolute values make no sense - you only have to take absolute value once to get rid of all the contained signs.
If you’d ever taken any advanced math, you’d see that the answer is 1 all day
Don't need to do advanced Maths - every rule you need to know for this problem is taught in Year 7.
It's totally clear. It's a number divided by a factorised term, as per The Distributive Law and Terms.
It's the first, as per The Distributive Law and Terms. It could only ever be the second if the 6/2 was in brackets. i.e. (6/2)(1+2).
Indeed it was already solved more than 100 years ago. The issue isn't that it's "ambiguous" - it isn't - it's that people have forgotten what they were taught (students don't get this wrong - only adults). i.e. The Distributive Law and Terms.
No, it doesn't. It never talks about Terms, nor The Distributive Law (which isn't the same thing as the Distributive Property). These are the 2 rules of Maths which make this 100% not ambiguous.
Yeah, base ten really screws around with programming. You specifically have to use a decimal type if you really want to use it (for like finance or something), but it's much slower.
Also noted that you've declined on taking on that bet I offered.
