+        """
+        Return Multiplication of series and other, element-wise (binary operator `mul`).
+
+        Equivalent to ``series * other``, but with support to substitute
+        a fill_value for missing data in either one of the inputs.
+
+        Parameters
+        ----------
+        other : Series or scalar value
+            With which to compute the multiplication.
+        level : int or name
+            Broadcast across a level, matching Index values on the
+            passed MultiIndex level.
+        fill_value : None or float value, default None (NaN)
+            Fill existing missing (NaN) values, and any new element needed for
+            successful Series alignment, with this value before computation.
+            If data in both corresponding Series locations is missing
+            the result of filling (at that location) will be missing.
+        axis : {0 or 'index'}
+            Unused. Parameter needed for compatibility with DataFrame.
+
+        Returns
+        -------
+        Series
+            The result of the operation.
