Math symbology question
-
Oh, now that's an idea. Thanks. :thumbsup:

Sure it's not a printing error? A multiplication sign that is messed up? That would make the most sense to me at least.
This is in line with my thinking. I've seen multiplication represented by an 'X', an '*' (asterisk), a dot, and an open dot (circle). Maybe they were going for a dot or open dot, but the character set the printer used didn't have an exact match. The anti-clockwise arrow may have been the best fit. (Why they didn't replace it with a common alternative like 'X' or '*' is anyone's guess...) Of course then you have to ask what business the printer has printing math books without a sufficient character set... But that's another conversation entirely...

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've asked some maths experts and they've requested more information. Do you have earlier pages in the chapter you could post? So far nobody has seen this symbol used in this way.

Nope, this is just a worksheet we think the teacher downloaded from the 'Net. So it is likely a mis-translation of some sort. Interestingly, the next day the kid brought home another worksheet and my wife was able to find it -- with the answers. :cool: We're not impressed by the quality of the "teaching" that goes on now.

If it's not too much trouble, what were the answers? Was it a multiplication symbol as suspected?

Apparently the books are supposed to stay in the room.
Guess where the knowledge will likely stay. Effing school boards, I'll bet the Supervisor makes a great deal of money, while "saving" so much on the education of children.

How old is your kid? If he/she is primary school pupil then the sign is just a incorrectly rendered multiplication sign. There is absolutely nothing else you can do with c ^ (12/5) and c ^ (3/5) but to multiply them. And solutions are 13) c ^ 3 14) x ^ (21/4) (unless part of formula is missing on right) Or the question was just for laughs ... :cool:

It's supposed to be algebra 1, 9th grade. And it's likely supposed to be multiplication.

If you know the name of the book and the page number, then you might be able to find an errata. Most printed text books have pages and pages of errata. If they do not let you bring the books home, then there is probably an online version with some lame password like schooldistrictname2015. Hopefully, the online version would be fixed but you might still need to find an errata.
