[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1 <2 <3 <4 <5 <= 5 >4 >3 >2 >1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 9 inequalities：
        1 <2         (1)
        2 <3         (2)
        3 <4         (3)
        4 <5         (4)
        5 <= 5         (5)
         5 >4         (6)
        4 >3         (7)
        3 >2         (8)
        2 >1         (9)

    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 inequality(4)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(5)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(6)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(7)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(8)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(9)：
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (12)
    From inequalities (5) and (12)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (13)
    From inequalities (6) and (13)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (14)
    From inequalities (7) and (14)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (15)
    From inequalities (8) and (15)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (16)
    From inequalities (9) and (16)
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (17)
