[ 1/1Inequality]
    Assignment:Find the solution set of inequality -1 ≤m ≤2m ≥2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 3 inequalities：
        -1 ≤ m         (1)
         m ≤2 * m         (2)
        2 * m ≥2         (3)

---

    From inequality(1)：
         m ≥ -1
    From inequality(2)：
         m ≥ 0
    From inequality(3)：
         m ≥ 1

---

    From inequalities (1) and (2)
         m ≥ 0    (4)
    From inequalities (3) and (4)
         m ≥ 1    (5)

---

    The final solution set is :
         m ≥ 1
