A [          ][3] )
O [          ]       ) 57

2 u --> 57 - 3 = 54
1 u --> 54 ÷ 2 = 27
A --> 27 + 3 = 30

    [][][3][][3]
A [][     ][     ] 30    A - O --> [      ] - [] = [3],
O [][][     ]      27   so redraw [     ] as [][3]

3 u --> 30 - 3 - 3 = 24  1 u  is different from the earlier 1 u
1 u --> 24 ÷ 3 = 8         If you like, you may use 1 su

30 - 8 = 22 apples
