Math symbology question
-
My kid's algebra homework contains a symbol like an anti-clockwise arrow, sort of the opposite of ↻ (if it'll display). It's mixed in with "rational exponents" and my wife and I have never seen them. We have been unable to figure out what it means and the kid doesn't seem to know. Edit: http://www.codeproject.com/script/Membership/Uploads/2587207/Math.png[^] Any of the younger folk know what it means?
I haven't searched, but you could try looking for it in Latex and seeing if that offers any clues via name/documentation etc.

My wife and I both searched. Even Wolfram seemed to just shrug. We wouldn't be surprised to find that it's the wrong symbol. Or some cockamamie new "common core" X| thing.

I thought the same thing. Why not go to the teacher first. :doh:

So I would think, but they weren't issued books. :sigh:
Crazy. That's probably why QA has so many requests to do homework. :confused:

Sure it's not a printing error? A multiplication sign that is messed up? That would make the most sense to me at least.

Have not found it anywhere though have tried even image search, definitely not standard math symbol. Its either printing error or an individual attempt to map a shaky concept into self created image.

The rational exponents can only simplified if the symbol is a division. If you multiply 12/5 * 3/5 you get 36/25 which cannot be simplified. The other way around 12/5 / 3/5 = 4 makes a lot more sense. Same for the other expression.

This is most likely a Unicode error. I think the "vertically middle dot" was meant to be printed out. Do you have other exercises you could relate to ?

I think that's the "turn around and ask the smart kid hiding in the back row for the answer" symbol.

This might not help at all but makes you feel less guilty. I work now 20 years in Reinsurance and develop pricing tool, have a degree in Electronics and Economics. My work colleagues, who are by nature, all mathematicians and specialist in the field of actuarial science. Some have PHD's and other degrees I cannot even pronounce. However, I haven't seen this symbol in my entire career, and that's frustrating! Could it mean to find a divisor to get from c^12/5 to c^3/5? Have a look here on Wolfram https://www.wolframalpha.com/input/?i=(c%5E(12%2F5))+%2F+(c%5E(9%2F5))

A math class. With no books. Western civilization is doomed. With any luck, the teacher will be mounted to the front of the savages' leader's vehicle when they storm the refuge of the survivors...

I haven't taken a math class in 30 years, but 30 yrs ago, I took a lot of them. Even so, the algebra problems your kid is doing hasn't changed much since the 17th century. Find the earliest reference in the book, or perhaps even inside the cover. I strongly suspect the author has minted his own notation. In context, it looks like you're supposed to replace the squiggly with another standard symbol, such as < etc.

Except that a multiplication symbol there would mean you add the exponents together, not that you multiply them. For example: `c^2 x c^3` equals `c^5`, not `c^6`. Therefore, if it is multiplication, you will actually be doing: `12/5 + 3/5` which is `15/5` which simplifies to `3`.
