Put the eight numbers 2, 3, 4, 5, 6, 8, 10 and 12 into the following spaces to make the four sides in the figure add, subtract, multiply and divide () * () = () / () = () + () = () - () = first bracket

Put the eight numbers 2, 3, 4, 5, 6, 8, 10 and 12 into the following spaces to make the four sides in the figure add, subtract, multiply and divide () * () = () / () = () + () = () - () = first bracket

() * () = () / () = () + () = () - () = the first bracket can be regarded as () * () = the first bracket. Because there is no number 1, the eight numbers cannot be filled in the following spaces respectively
