You need to know a wide variety of things. Make sure that you have all the topics in algebra, geometry, number theory, and counting and probability down because those are the big 4.

Hi there, My name is SVS

Welcome to Web2.0Calc!

Here is a forum where you can ask and answer math questions.  

This site is really cool and I enjoy it a lot. 

Hope you enjoy it also!

Everyones really nice here (except trolls)

But still Welcome!

(You earn points by answering and asking questions)

Once I fell into a sewer but I pulled my self out. It was scarier then funny. The Snow had covered the potholes and the people had left it open. If I had let go..... :/

Thank you for illustrating my point, CalculatorUser!!!

But seriously, everyone just stop downgrading people!

(What does vigilante mean?)

Ooooh, Ouch Leaded, But I still agree with Melody.

Thank you!

Correct!

Great job!

Then you do this:

   _____

12)500

You solve and get 166 R2.

After that, you just 125/3.

That is about 41R2.

So you would have:

41*12...

492?

Agree! Wonderman, stop acting like some VIGILANTE POLICE bossing around the site. You are being really rude.

Seeing your history, all you ever did was just downgraded other people's solution.

AOPS or the class resources may not have explained the solution fully or wel enough, do not just assume that ABJ11 is cheating.

Yep!

Okay, so you take Twelve, right?

Sure! Give it a go!

Can I try?

Let us start out by finding the LCM.

From that point on, can you solve it, or would you like some more help?

492.

492 / 3 = 164

492 / 4 = 123 

I do understand that you are trying to help, but please do not accuse people.

I was told once in a PM that I was copying problems off a website, more known as AoPS.

(I was, in fact, trying some advanced problems one of my math tutors gave me. The problems I post here are the ones I have pondered over for a long time.)

(I also am posting work on my questions when possible.)

Needless to say, your contribution to this website is deeply appreciated, however, I would like to ask people to help people out, but encourage them to find their own solution by simply posting hints.

Please ask yourself in the future whether this person may be genuine.

I would say 22.

5 x 6 x 7 = 210

14 x 15   = 210

5 + 6 + 7 + 14 + 15 = 47

Point X must be in three small equilateral triangles, each with side length.  Each small equilateral triangle has 1/9 the area of the large equilateral triangle, so the probability is 3/9 = 1/3.

yes, sorry for being vague. I do not like to say dirty things.

(k-9)(k+9)

a) Adam Smith 

Gives = (108-18)x      Where x = number of weeks    

    She gives the same number away each week : (108-18)

      each subsequent week increases the total number she has given away....
