Expression ((3*4) + (2*(12^2))) - 2 consists of 2 subexpressions: ((3*4) + (2*(12^2))) and 2 connected by the `-' operator, so ex1 = Sub ex1_2 2 where ex1_2 is an Exp representing ((3*4) + (2*(12^2))) which is a sum (Plus .....). -- WBR, Max Vasin. _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
