I was hoping I'd start some long debate between people, but alas, that's correct. T.T

Oh. Wow, that is a wonder... Ahahah. Alright, I'll also share my thought if that's okay.

I'd like to imagine that the calculator answered 0 because of its primal function which is to count (regardless of the mode of computation like MDAS). If it counts "20" by zero times, then it means that it didn't count it at all. Therefore, the answer is 0 or none. For the calculator to say that the answer is 20, it needs to count it once (x1)... even though if you think about it, multiplying 20 by nothing should have still left it as 20... v_v

But, yes. I do agree that the answer should be 10. Multiplication, then Addition. :wink:

Ah! Also, sorry for butting in... I'm kinda new around here - but I've been lurking for sometime now...so, uhm.. Hello! :D

BTW, have the thread author/creator (Mugenjohncel) said anything? It's been quite some time and the discussion have spanned across three pages. In case I missed his post... but is there any reply from him?

It's a link that to Mugen's post (which is in this thread too). So it's same thread but different page.

If you follow any link that's in a thread wether you have already seen it or not, well, then, yes, there's an infinite loop ;-)

Reading that blog reminds me that there are many ... *beeeep* people in this world. They are so sure of themselves, insulting other people as they like, and yet they did the same mistake as people they insulted do... which is making mistake.

I just asked my twin sis about it :

Me: *ask her*
twin: You don't have to ask, it's zero .
me: I think it's 10
twin : 0 x any number = 0 .. simple as that !
me : yeah 10 + 0 = 10 !
twin : 20 x 0 = 0 !
me : why not 10x0 = 0 then adding the other 10 ?
twin : no, they wrote 10 + 10 x 0 , do 10 + 10 first.
me: there's two answers then = p
twin : it's cant be, This question is stupid .. :evil: (goes away)

oh god even we're twins and our math grades were always the same.. we had two answers =_="
I think it's all about where you start, isn't it :wink: ?

I think it's been mentioned before but here it is again:

There is only one way to start. You have to follow the order of operations to do it correctly. Even if the problem doesn't necessarily say to use PEMDAS, you still must to get the correct answer. So you would have to multiply the 10 and the 0 first then add 10. I'm fairly sure several people have said it but I felt like adding my input :P

So, the correct answer is 10. Anything else is wrong.

It's just because those people (who answer zero) simply doesn't know the "rule" to count the formula (the PEMDAS). Perhaps they just doesn't pay enough attention in basic math class or never attend a computer science class.
