I am ending with no operator in the end. So 1000 160 would be the answer or what. I do not know what to do from here. Please help!

Yes you end up short one operator, so you have nodes containing 1000 and 160 with no operator to join them.

So 1000 and 160 is the answer. And did I draw the Binary Tree right?
