2 i 1/3 * 10 - 2 : 3 i 1/3 = 7/3 * 10 - 2 : 3 i 1/3 = 70/3 - 2 * 10/3 = 70/3 - 20/3 = 50/3 = 16 i 2/3
2 i 1/2 * (3 - 1/3 : 3) = 2 i 1/2 * (3 - 1/3 * 1/3) = 2 i 1/2 * (3 - 1/9) = 2 i 1/2 * (2 i 9/9 - 1/9) = 5/2 * 2 i 8/9 = 5/2 * 26/9 = 65/9 = 7 i 2/9
7 i 2/17 - 3 i 11/17 = 6 i 19/17 - 3 i 11/17 = 3 i 8/17
6 i 2/5 + 8 i 5/6 = 6 i 12/30 + 8 i 25/30 = 14 i 37/30 = 15 i 7/30
5 i 2/3 - 2 i 3/7 = 5 i 14/21 - 2 i 9/21 = 3 i 5/21
