thank you Melody!

or 

Its an honor to hear this from you my Queen!

Thanks Rosala.  

There are a lot of ways to explain this concept.  You gave a good answer  :)

aww why didnt i think that!anyways i was just trying to give a " detailed" answer like you Melody so i wrote it!anyways nice example!

i'll give u a point for that!

Also

If the temperature was -9 degrees and it gets 9 degrees warmer then wouldn't it be 0 degrees?

the simplest rule!

the more you practice maths the better you get in it!

so just follow this and see how u will be climbing heights!

we get the answer zero becoz when in integers when we add a postive integer and a negative integer then we have to subtract them and so if we subtact two same numbers like 9 then we het a zero!its just like 9-9=0

so 

(-9)+9

= -9+9 

= 0

just like 

9-9

= 0

okay!so i hope now u have understood !and if not then we're here to help you!

It would come out to -15.

Say you owe someone $9, (which is -9) then tomorrow you owe that person $6 more (which is the -6)

How much do you owe them now? Well, you owe them $15 so the answer is -15.

Whenever your measuring distance, or something like it, you abolute the numbers your subtracting.

For example, say you have these two numbers on a number line and you want to find the distance.

You wouldn't just do -2 -1 to find the distance, because that would give you -1 and that doesn't make any sense.

You would want to do |-2 -1| which would be |-1| and then 1. The distance is 1. That makes more sense.

Anyway, let's apply this to your question. The temps. range from -122 to 30. To find the difference, subtract them in absolute values.

|-122 - 30|

|-152|

152

So the difference in the temps. on Mars is 152 degrees celcius.

8=4q-4

12=4q

q=3

1/(2*2*2)

1/2^3

2^-3 = 2^n

n=-3

w^(-2*3)/w^-8

w^-6/w^-8

w^(-6+8)

w^2

Yes sorry, sometimes I get carried away.

Like I said, when it is just in print it is hard to pitch it correctly.  

Now you are giving me homework?  A l r i g H t .  

Thanks Alan, I really should look at that!  You are right   

Sorry

I was thinking it was just a skin (press metal)

Add the terms involving y:

7y + 6 = 20

Subtract 6 from both sides:

7y = 14

Divide both sides by 7:

y = 2

Click on the "2nd" button.  They appear as asin, acos and atan respectively.

but your comment is very harsh 

If it's a solid sphere and you turn it into a solid cube, then the mass will stay the same, and because the density is the same, the volume will also be the same.

Volume = (4/3)*pi*8³ cm³

If side of cube is of length L then L³ = (4/3)*pi*8³

The surface area of the cube is 6*L² = 6*(4*pi/3)^2/3*8² cm²

That's ok, I am sure that you didn't mean to be rude.

You just have to be careful when you are communicating with just print.  People can't see your body language or your facial expressions so it is easy for them to misinterprete your intent.  

!!!!! thank you melody !!! 

very nice alan =D I undrstood that 

$$\\c^2=161.44\\\\
c=\sqrt{161.44}\\\\$$

Just do it straight on the calc on the home page.  

You can either type it in as  sqrt(161.44)    or you can use the  $$\sqrt$$  sign

$${\sqrt{{\mathtt{161.44}}}} = {\mathtt{12.705\: \!904\: \!139\: \!414\: \!872\: \!8}}$$
