Дано: a = 1/3, b = 2/9, c = -2/3
Вычислим значения выражений:
- -a + b - c = -1/3 + 2/9 - (-2/3) = -3/9 + 2/9 + 6/9 = 5/9
- a + b + c = 1/3 + 2/9 + (-2/3) = 3/9 + 2/9 - 6/9 = -1/9
- a - b - c = 1/3 - 2/9 - (-2/3) = 3/9 - 2/9 + 6/9 = 7/9
- a - b + c = 1/3 - 2/9 + (-2/3) = 3/9 - 2/9 - 6/9 = -5/9
- -a - b - c = -1/3 - 2/9 - (-2/3) = -3/9 - 2/9 + 6/9 = 1/9
