   Hello all, this is my first post on these forums and I'm a fairly new user of AutoCAD. 
I've been using the dynamic input field(s) often but have often felt the urge to input some simple mathicmatical equations (264-39 for example when extending a line) but the program won't take it.
It has worked on very rare occasions but I have no real clue how. Is there any way to ensure this works to make AutoCAD know it's supposed to handle the input as an equation instead of a sole value?
Thanks In Advance :)

	You can directly use integer division ("/"). For other expressions you can use the AutoLISP notation - e.g.: (- 264 39) *( 6 7) (/ 22.0 7.0) (+ 1 2 3 4 5)**

	It does appear to work, but I wonder why it will recognise a division but nothing else? Doing it with the AutoLISP notations is quite cumbersome :(

	The data entry doesn't support expressions - the division only comes from the fraction data notation. But LISP expressions are quite easy - all must be in round brackets, first comes the function, then its operands.

	Thanks, it's easier to understand written in English. Brackets -> function -> operands... cool! Edited by Kev_Boy - 22.Apr.2008 at 11:39
