[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4 <78 >56 >45 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 3 inequalities：
        4 <78         (1)
        78 >56         (2)
        56 >45         (3)

---

    From inequality(1)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(3)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (4)
    From inequalities (3) and (4)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (5)

---

    The final solution set is :
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
