Nancy Drew 19: The Haunting of Castle Malloy Easter Egg - Leprechaun Egg

Go to the ring of stones in the yard where the sheep are (past the stone wall that you have to open). If you've moved any of the stones at all, back away from the pillars completely to reset them. Number the stones like this on the lead pillar (the one with the stone on the ground in front of it):
1
2
3
You want to turn them in this order and this number of times:
1 (twice), 2 (three times), 3 (once), 1 (four times), 2 (four times), and 3 (four times). Something should happen.

To get the egg: Follow the directions above to get your clue from the stone pillars. Once you have the piece of paper with the shamrocks and math equations, you need to solve each to get seven different answers. Now go to the gnomes. Using the seven answers you just got, turn the gnomes as you would to the numbers on a clock.

The answers to the puzzle are:
(1) 3, (2) 6, (3) 9, (4) 9, (5) 12, (6) 12, (7) 6

For the directions to turn the gnomes and which gnomes to turn:
I've numbered them from left to right like this:
1 2 3 4 5 6 7

Turn 4 to 3:00, turn 1 to 6:00, turn 6 to 9:00, turn 2 to 9:00, turn 7 to 12:00, turn 5 to 12:00, and turn 3 to 6:00.
