In other words, bing now has some calculation abilities. MS is running an ad with this particular calculation suggested as a Bing search and a background photo of a blackboard.

Well, as you see, it works. And (I presume) they would like you think about the fact that throwing the same equation at Google does nothing useful (inexplicably, the first result was a page about BSD).

But I wonder how many users of this feature will be familiar with the rules of operator precedence? I admit I read it as:

x-3

--- = ... << I can't format it right but you get the idea

x-1

After testing it with Google, I went to Alpha, which (unsurprisingly) handled it with aplomb, giving it to me with proper notation as well and making me aware of my mistake. So I tried it as (x-3) / (x-1) = (x-4) / (x-5), which Alpha also handled with Aplomb (11/3 if you are lazy).

However, inputing the latter into Bing (without or without spaces for padding) gave no calculation or result, but just a bunch of (mostly unrelated) search results. Seems rather counter-productive on MS's part.

Apologies if this is excessively trivial.



Even weirder...

(x-3)/x-1=(x-4)/x-5 works OK (ie Bing treats it as math); indeed for (x-3)/x-1=x-4/x-5 Bing properly gives both solutions 1/2(5+/-(29^0.5)).

But it absolutely Does Not Like parentheses in denominator (eg x-3/(x-1)=x-4/x-5) on either side of the equation. Clearly, I need to get out more.


google of course now links to this page first!
