I always try to bulid programs so easy that they don't need a step-by-step help. The interface of this program is the standard Windows one, the only operations an user can found difficult to do is insert a momomial.

In the grey box
1,2,3		1,2,3	
-1,-2,-3	-1,-2,-3
+1,+2,+3	1,2,3
-		-1
+		1
[Nothing]	1

In the white ones
a3		a^3
b9		b^9

B9		ERROR

In order to reach all the upgrades (abt. 1/3 of the program size for the same features) by mail... MAIL!
