For No. 6, move the top right stick of the 3 across to the top left of it and move the top right stick of the 9 down to the bottom left of it, so that it says 1 + 5 = 6 Or, here's a novel way of doing it that I've just seen: move the top stick of the 9 over to the top of the 1 and move the bottom stick of what was originally the 9 to in front of the 3, so that it says 7 + -3 = 4
