I'm stuck on page 17 , the bottom one ( clue#14 - clue#15 ) is not the problem but the one on top of that. I have clue#16 but that one doesn't make any sense to me. Maybe it's because we use different measurements and math over here ? ( i'm from The Netherlands ) Just a little hint would be very helpful, i know there are only 3 digits left and i already tried every combination possible.
edit: i got it. Thanks for the help
