if its a number one then you do not even need the clue. if both of the two circle thingies have numbers on them and you have to figure out for example 917 _ _ _
just try 917 028 139 240
etc. (this is just adding 1 to each of the numbers) Or you could look for the clues in the pictures where as stated it will have something like 6 = 4 what this means is align the two circles so that 6 = 4. Then replace the numbers you are supposed to solve with their equals judging from the 6 = 4 circle.
