[ 1/1Inequality]
    Assignment:Find the solution set of inequality -0.05 <= (500x-0.01357-503.53533x+252.62243x^2)/(500x) <= 0.05 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -0.05 <= ( 500 * x - 0.01357 - 503.53533 * x + 252.62243 * x ^ 2 ) / ( 500 * x )         (1)
         ( 500 * x - 0.01357 - 503.53533 * x + 252.62243 * x ^ 2 ) / ( 500 * x ) <= 0.05         (2)
        From the definition field of divisor
         500 * x ≠ 0        (3 )

---

    From inequality(1)：
         x ≥ -0.085595
    From inequality(2)：
         x ≤ 0.11343
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         -0.085595 ≤ x ≤ 0.11343    (4)
    From inequalities (3) and (4)
         -0.085595 ≤ x < 0 或  0 < x ≤ 0.11343     (5)

---

    The final solution set is :
         -0.085595 ≤ x < 0 或  0 < x ≤ 0.11343
