Are you bored of real doors? Just having to open and walk through them all the time?
I'm waiting for the time when I can walk through walls.

Under a section in this forum such as Help Me, Members only, Exercises and so on, you see under that written as "moderated by ---" . Such as In Help me, you will see, moderated by Ricky, bob bundy, ganesh, mathsyperson. May I know what is that?
Different moderators and administrators are assigned to moderate threads within a specific section.

Please give all answers
Can't see the questions clearly.
An advise:
Math isn't about the answer, it is about how you get to the answer (many ways).
For competitions like Kangaroo Math, you are not allowed to use calculators, think out of the box.

What I would suggest is ask David's question to one person.You would come to know whether he is knight or knave. then you ask him to list who are the knights.Two questions are enough.
Wow. Nice
#33 Re: Help Me ! » Knights and knaves » 2016-12-07 22:58:58
Can you ask the same person more than once?
Exactly, I was thinking about that.

To be precise,
The minimumof minimum number of yes-no questions that he must ask the inhabitants is 5.
The maximumof minimum number of yes-no questions that he must ask the inhabitants is 9.
But the question doesn't specify.

On a fictional island there are 10 inhabitants, who all know each other, of which 5 are knights, who always tell the truth and the rest of them are knaves, who always lie.
A visitor to the island wants to determine the 5 knaves. What is the minimum number of yes-no questions he must ask the inhabitants in order to find the 5 knaves?
Knights always tell the truth, knaves always lie. Ask them a fact question. => Do you live on an Island?
Knights will always tell the truth, hence, they will all say yes.
Knaves always lie, hence, they will all say no.
The minimum number of yes-no questions that he must ask the inhabitants is 9. (5-yes 4-no/ 5-no 4-yes) At 9, there's enough information to find out the 5 naves.
#36 Re: Help Me ! » I have an algebra project that could fail me :( » 2016-12-01 14:41:20
So
I have a project for my algebra 2 class and I do not know how to do it. It is make a "quadratics for dummies" article. You see I am the "dummy" in this scenario and how is the "dummy" supposed to make a article for the "dummy"? Its all rather demeaning you know. Anyways the specifics of the project are that
A. I have to create an article simplifying the directions for analyzing and solving quadratic functions taking into account complex numbers.
B. Formulate a theory for predicting when each of the described methods should be used for each particular function (I think the three ways are completing the square, factoring, and using the quadratic formula).
C. Create a graphic organizer such as a flow chart or a flow map to show your recommendations.If anyone could help me with this I would be ecstatic. Really!
Any help would be appreciated.

But it seems that, for the members and moderators of this forum, they have mostly moved on with their lives, rather than migrating to AOPs, SE, MO, etc.
Some might have moved on to afterlife... oops...

So guys, let me get this straight.
I'm trying to be active in this forum as much as possible, but schoolwork seems to prevent this.
It's now our break, so I have LOTS of time to see how the forum's been doing while I was away.
So yeah, hello!
Hello!! I have 2 weeks left for my final exam. Then I'm free! Yay! Welcome back!

Hello,
I don't know if there are other italian users, I'm here because Italian Math Forums are really boring because of their inactivity. I'm really young (fifteen) but I have a great passion for math and I really like to solve hard problems and puzzles. I'm sorry if my English isn't perfectly correct , but I'll do my best.
Hi;
Welcome to the forum!
We have some users of Sicilian ancestry.

#49 Re: Guestbook » Questions about American Culture » 2016-08-14 05:47:43
That is a long and difficult answer. To go into it I would have to rant for about 30 minutes. It is Sunday, a day of rest, the Sabbath, a day without rants.
Sabbath is Saturday!
