• 5/6 - 2 = 5/6 - 12/6 = -7/6

• 7/3 - 2 = 7/3 - 6/3 = 1/3

• 5/6 + 7/3 = 5/6 + 14/6 = 19/6

• 1/4 - 19/6 = 3/12 - 38/12 = -35/12

• -35/12 - 7/3 = -35/12 - 28/12 = -63/12 = -21/4

• -21/4 - 1/3 = -63/12 - 4/12 = -67/12

                1/4

        19/6   |   -35/12

    5/6 |   7/3  |   -21/4

-7/6 |   2   |    1/3   |    -67/12
