Solving 9||2: Strategies for Computing the Unknown

[ness9660]

How would you compute the following,

9||2

Ive never seen this previously and i can't consistently match answers the book has for the various listings.

I'm sorry, I honestly don't recognize that notation. Could you give us more information? Can you find the first place in your book where it appears?

I suspect it is a typo.

It would be best if you could provide the context in which it appears, preferably a direct quote.
This would hopefully enable us to establish what the author has meant.

In many programming languages, it means "or", but I don't think that's what they're trying to say here, since "9 or 2" doesn't make any sense on its own.

 

[arildno]

How about 9 is parallell to 2?

No, that doesn't make a lot of sense either..


I'm sorry, SpaceTiger, I just couldn't resist, even though I know your suggestion CAN have some sense in some context. Mine can't (I think..)

Well, I figured there was some chance they had seen something like (x<9||2<y) and interpreted the "9||2" part by itself.

That is indeed a good suggestion if it is not a typo..
