Him breaking it would have been against the rule about "only 2 breaks". The only other rule was that every day you had to give him some gold.
It isn't a trick, it's called lateral thinking. It becomes obvious when you realise you have only 3 lots of gold and 7 lots to fit them into. You can't split 3 across 7 without breaking it down, so you have to think a bit more. Given that the only two people in this scenario are you and him, passing gold back and forth as "change" becomes logical, and you only need to figure out which breaks to make.
It's a bit like the fox, chicken, and wheat problem. A farmer needs to get them across the river, but the boat can only take him and one of the aforementioned items. Left alone, the fox wil eat the chicken, and the chicken will eat the wheat. The answer to the riddle involves taking items across and taking them back, so that you can transfer all items across without anyone getting eaten. Nowhere in the riddle does it say you can take things back across once they are on the other side, but it doesn't rule it out either.
No need to throw a tantrum when you can't figure out the answer.
