[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <(-0.2396-23.56*D)*(-0.495-46.61*D) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 < ( -0.2396 - 23.56 * D ) * ( -0.495 - 46.61 * D )         (1)
         ( -0.2396 - 23.56 * D ) * ( -0.495 - 46.61 * D ) <1         (2)

---

    From inequality(1)：
         D ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         -0.040573 < D < 0.019783

---

    From inequalities (1) and (2)
         -0.040573 < D < 0.019783     (3)

---

    The final solution set is :
         -0.040573 < D < 0.019783
