I have some more Rebus puzzles:
Seeing how the first lot were a bit easy I decided to make these a bit harder. Good luck!
HINT FOR 3:
It has something to do with the fact that they are numbers i.e letters wouldn't work
Hint for 3 and 4:
For 4, it has something to do with the positioning of a certain letter/letters. For 3, there is no summing involved and the underlining just under lines the last number
Next lot: Even more rebus puzzles!
