Life is a biologic thing, something is alive if it breaths, and a couple more things, see google.

Now stop asking questions like what is maths, what is life that's not what this forum is ment for.

I believe it's a type of grain.

Maths is the short form of a word "mathematics "!

 but i have answered u already , the answer is 30    !

But reinout u just lighten half of my day , what about the left half , wholl lighten that !

Oh melody !pls dont say that to me! i just love ur wraps ! if u want i can give u two thumbs ups (on two different wraps )! and btw u were absolutely correct on saying "hello to everyone"in hindi ! but thats language is too formal to speak for me and i dont speak it , infact no one mostly speaks it !my language is good but totally different from this , its not as formal ! but i like speaking english the most , actually i just love speaking english !but u were good in writing the correct hindi !lol!so two thumbs up from me !and "aapka bohot bohot dhanayvaad " thats thank u very very much in too formal hindi !

Hey reinout, I'm definitely a her.  Not that I mind and all that.  I can get a bit confused. Umm what was i saying again?  

haha no, i don't make these myself.

I thought if melody posts her end of the day wrap up every day.

What if I post my begin of the lunch box unwrap every* day?

Every lunch box has some funny math joke inside (which I find somewhere on the internet).

just to lighten up your day a little .

Do you like the idea?

*every in the sense of, when I'm here

thank u very much melody !

सभी को नमस्कार    

According to Mr. Google, this says hello everyone in Hindi.  Hindi is Rosala's primary language.  I am sure that she will correct me if I am wrong.

Rosala, thank you for wishing me a good week.  But I am wondering why you didn't like my wrap.  I am sure if you liked it you would have given me a thumbs up.  lol

Great answers today from Rosala, CPhill, Alan, reinout-g, zegroes, NinjaDevo and Heureka.  Thank you all. 

Here are the interesting posts for the day:

#Introductory Calculus (do you think this one might be worth adding to your list Ninja?)

eh ! what do u mean ?

Thank you Jedithious.

We always appreciate your excellent manners too!

52 letters to choose from 6 letter permutations  That is 52P6

$${\left({\frac{{\mathtt{52}}{!}}{({\mathtt{52}}{\mathtt{\,-\,}}{\mathtt{6}}){!}}}\right)} = {\mathtt{14\,658\,134\,400}}$$

The ns cancel out

denominator is the number below the line in a fraction ! for example : 2/5 is a fraction (proper fraction) and the denominator in this fraction is 5 and the numerator is 2 ! i hope u might have understood now but if any doubt still exist , pls be free to ask !

It's the term at the bottom of a fraction. E.g. = 1/2 ; 1 here is the numerator, it's the term at the top while 2 is the denominator, it's at the bottom.

Thumbs up from me for both of you.

cos^-1(x) ,  arccos (x)  and acos(x)   can all be used to denote the cosine inverse........the on-site calculator uses acos.......just hit the "2nd" button to access it......

Ah fate doomed to walk the 2D world alone with out anyone else....

okay so can you get the same calc answer as me?

yes , i can find them !

It is not slang zegroes.

You just need an ordinary dictionary or you can just google it!

What is the volume of 425 g of ice, if the density of the ice is 0.92 g/mL?

Something that people often do not understand is that you can cancel units just the same as you can cancel numbers!

This is what you have.    

$$\frac{425g}{1},\quad \frac{0.92g}{1ml} \qquad \mbox{ and you want to find a volume which is mL}\\\\
\mbox{Put the mL first and on the top}\\\\\
\frac{1ml}{0.92g}\times \frac{425g}{1}=\frac{1ml\times 425}{0.92\times 1}=462ml\quad \mbox{to the nearest ml}\\\\$$

NOTE: 

1) The grams cancelled out.

2) When fractions have units it is alright to turn them upside down.

for example 5km/1hour is the same as 1 hour/5 km
