Absolutely in the expression editors marked with an "e". Also modulus (%) and concatenation (..) in addition to the drop down list of functions and the attributes.
e.g.
Change Attribute ` self.Position.X -> game.Screen.Width / 2 ` (Unless I'm misunderstanding your question, this is pretty basic and core to a lot of the Wiki examples, demos, etc.)
Thanks CodeMonkey...I should have mentioned that too. I forget that some folks here may have no prior programming experience (or even spreadsheet experience) where they would have learned that the operators are actually different symbols.
