I think I have interpreted it differently from CPhill

this is my interpretation

ok, i thought i had to answer them in latex and workings showed i'll try  them quicker under.

Q2) 5x*6yx=30xy

Q3) 3(x+4)=12x    -      (3*x)+(3*4)=12x

Q4) -2(x+4)=-10x         -       (-2*x)+(-2*4)=-10x

Q5) 17 - 4x -x +5=22+(-5x)        -         (like terms -x & -4x and 17 & +5) 17+5=22   /    -4x-x=-5

Q6)3-4(5x-6)=23x+24           -  (Not sure but...)   (-4*5x)+(-4*-6)=-20x+24        +    (3*5x)+(3*-6)=15x+(-18x)   15x+(-18x)-20x+24=-23x+24

Q7) 3x/2 + 4x/5 = 12x+10

Q8) 0.06*0.3=0.018        (6*3=18/1000=0.018 )

Q9) 0.06/0.2                  (6/2=3/1000=0.003)

Q10) 3x^2 +2x +5= 3x^2+2x+5       (Like terms none) the answer is given

Q11) 5x+2/6y * 9xy^2= ....Have no idea. 

WAIT.  9xy^2 as a fraction...ah

zero

Or at least it tends to zero

That does not look like the surface area of a cylinder to me.   

Your calculations looks good though zac  

why didnt you tell me about it before!its done...your silver ranger...so much of power hun?

Mathsgod...by this game....your imaginations will grow...when the other party will attack, it will compell you to imagine how to give them a good answer with witty words......it will be a good break after doing lot of LaTex!

my favorite color is light blue ....but i like being a red ranger!lol

Wow a book!

Good luck, now that's something i need - creativity - I'm way too serious in education, i lack the creativity for English.

As for colours yellow is fine if everyone has basic colour it'll be even.

(What's your favourite colour? Mines is Silver) :D

They are only suppost to be simple questions.  Can't you just do them all at once?

There is no x in there  

the last post was enough for them!

and oh common mathsgod...your a star....not a 12 year old.....im 14...im writing a book...now isnt that crazy....here we are all equal.....dont step back by your age!

NOTE EVERYONE:even a new born can join the teams(only if they know how to type and speak...haha)

so are you satisfied with your color!

any query....im here!

Yes this post is getting very slow.

I will continue question two in a  new post.

A ranger!

*gulp* well this is awkward, at first i wanted to join a team, but I'm a ranger.Lol

Who'd want to join a 12-years old team.

I'll keep my fingers crossed.

Also Rosala, were all the rules explained in the last post or are going to be in a new post? 

ofcourse you are...the queen of witty thoughts!haha

Oh yes Rosala, you said I am only good at 'grown up' humour.   That is really funny you know.    LOL

Maybe  im between them all........

Hang on a minute, if it is not a perfect square then it is irrational and it cannot be written precisely as a decimal at all.

$${\sqrt{{\mathtt{100}}}} = {\mathtt{10}}$$         exact

$${\sqrt{{\mathtt{6.25}}}} = {\frac{{\mathtt{5}}}{{\mathtt{2}}}} = {\mathtt{2.5}}$$       exact

$${\sqrt{{\mathtt{5}}}} = {\mathtt{2.236\: \!067\: \!977\: \!499\: \!789\: \!7}}$$        this is just an approximation!

'swear' at people with more 'colourful' symbols

#

now that is what i call a grown-up brain !ROFLOL!

Oh, you are very much a part of this forum Zac    LOL

But now I guess you can 'swear' at people with more 'colourful' symbols     

MathsGod1,

You cannot write an irrational number such as   $${\sqrt{{\mathtt{3}}}}$$    in digits.  NO irrational number can be expressed in digits.  You can get an estimate from the calculator but it is an estimate.  It will never be an exact value!

It has nothing to do with laziness.

Some countries (like Australia and I think the UK) shorten mathematics to maths.

and other countries like the USA shorten mathematics to math.

I am Australian and I used to think that "math" sounded really weird.   But, I am used to it now.  :)

In Australia we are lazy I guess because although we spell it maths, we often pronounce it as mass.   

right now points are the center ir attention.....slowly it wil go....this happens rarely but when it does...it comes like a stunami to everyone....lol

This conversation was happening here as well    :)

I was having this same conversation with Zac and Rosala.

Anonymous our God is absolutely right! But yes you still can play but with rules ! Wanna join my team! Pick up a ranger and get started! 

And mathsgod are you kidding me? You are in my team! I've already placed you as a ranger! I'll post that post after some time now!

The area of a trapezium is just the average of the parallel sides  times the perpendicular height.  

Well it will probably disappear again soon, or it could triple, whatever it does it is bound to entertain. :)
