I wish I could speak another language.  I find English hard enough. :/

I used to teach in an International College.  Many of the students had quite poor English. Admittedly I was teaching mathematics subjects but some, like commercial mathematics,  had an aweful lot of big words AND it was hard. I marvelled at how well most of them coped!

Hi all

Great answers today from Kallamoar, CPhill, Dragonlance, Complex, Omi67, Alan and abbypb9.  Thanks you  

Technical Issues:

How can you post a picture when the picture upload on the forum is not working properly ?

Thanks very much Alan for these instructions.

I live in a hot country too.  At least it is too hot to snow in Sydney.  It snowed (just once - it had never been recored before or since) where I lived when I was 4 but I don't really remember so I have never seen it snowing either.  :(

I've walked on a glacier but it wasn't snowing :/

I thought Complex's puzzles  they looked like they had good potential.     :)

Very nice answer and graph Omi :)

See how the two graphs are reflections of one another in the line y=x ? 

That is how it always is with inverse graphs :)

Are you still on the forum?

If you are about and still want me to try and explain more then I will do that.  

I need to here you 'voice' though :)

Like I said, I know at least one more answer (2 very slightly different versions of the same thing really)

Here is a big hint:    1000-55=945

Dragonlance please do not answer.  Let someone else do it.  

Yes, I did realize that halfway through my response. I thought "maths boards" and the penny dropped :))

I think I spelt is as I intended.   :D

Business cards are made of (card)board and they may be boring to some people but they do not normal hang out on maths boards (or forums)
