ive just started using mathematica from a server of my university (citrix), according to every tutorial of mathematica i should be getting at the prompt window, a line with In1:= but i don't see such a line.
and another thing, I've just started with basic arithematic operations, and it states that in order to see the output of say '1+1' i should press after typing '1+1' shift+enter, but it doesn't give any output.
how to reconcile this?

thanks in advance.

You won't see the In1 until you evaluate the line, i.e. <SHIFT>-ENTER. Then You will see the In1 and OUT1 line markers.

There is an option to turn the cell labels of/on (ShowCellLabel). Look it up in the on-line help (a great resource). Perhaps you need to turn them on.

Did the cell get evaluated?
 
i don't know really, i typed '1+1' (without '_') and then pressed shift+enter, and then the black line appeared i guess it bacause it passes to the next line.
anyway, the showcelllabel is it a command should i type it or what exactly?
i looked at it in the help browser but didnt understand how to check on it.
anyway, i checked in the cell properties and the cell is open,editable and evautable.
 
ok it works now, apparently i should have chosen at kernel-notebook kernel-local.
 
i have a few questions I am now using the tutorial here:
http://documents.wolfram.com/v4/MainBook/1.1.7.html
the special keys to enter input there I am having difficulty using for example this example of theirs:
N[esc p esc ctrl{^]2 ctrl{ctrl-space] ctrl{/]6ctrl{ctrl-space]]
now the esc is okay, but with the control should i press with one stroke or one continuous stroke?
thanks.

For the esc characters, it is sequential. Howver, when you are doing the control--- you do both keys at the same time.
 
the problem is how exactly to do it? i know it's funny but i need something like five fingers to do this.
it looks stupid to me to do this, but still it's good to know it.
