DECLARE @Table1 TABLE ( thing real)
DECLARE @Table2 TABLE (anotherThing real)

INSERT @Table1 (thing)
VALUES (1), (2), (3), (4), (5) 

INSERT @Table2 (anotherThing)
VALUES (6), (7), (8), (9), (10)
;

SELECT      T.thing * TT.anotherThing AS Multi
FROM        (
                SELECT  T.thing
                ,       (
                            SELECT  COUNT(1) RN
                            FROM    @Table1 AS T2
                            WHERE   T2.thing <= T.Thing
                        ) RN
                FROM        @Table1 AS T
            )AS T
INNER JOIN (
                SELECT      TT.anotherThing
                ,           (
                                SELECT  COUNT(1) RN 
                                FROM    @Table2 AS T2
