G'morning Aleksej,

Nah !  Start up the Microsucky Calculator and Notepad..

( Start>Programmes>Accessories>Calculator and again for Notepad )

.. and type out in Notepad the formula for, say, working out the 
probabilities of drawing 1 particular set of 6 numbers from 1 - 
40.

The National Lotto her in NZ relies on drawing the right 
combination of six numbers from 1 - 40,  and the chances of 
hitting the right combination are...

   40!/6!/34!=

Make sure the equals sign is there, highlight the whole line and 
paste it into the Calculator ( Edit>Paste ) - and watch the 
Calculator screen line as you hit Paste....

Now hit Edit>Copy,  click on the end of the expression just after 
the = sign,  and Edit>Paste again....

So what sort of ordinary calculator will take a programmer's 
calculation code and render an coherent answer that can be pasted 
anywhere ?

:-)
