+All Arithmetic in NSIS is handled by the [http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.10.2 IntOp] instruction.  It is beyond the scope of this task to implement user input (a fairly involved task), so I will be providing hard-coded values simulating the user input, with the intention of later adding the user-input piece.
 <lang NSIS>
+Function Arithmetic
-IntOp $0 1 + 3

-IntOp $1 $0 * 2
+	Push $1
-IntOp $2 $1 / 4
