[ 1/1Inequality]
    Assignment:Find the solution set of inequality b <-b/2 < > 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 3 inequalities：
         b < - b / 2         (1)
         - b / 2 <         (2)
         > 0         (3)

---

    From inequality(1)：
         b < 0
    From inequality(2)：
         b ＞ 0
    From inequality(3)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
