Overview: 2 questions will be solved this time.Among them
           ☆2 inequalities

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

---

    From inequality(1)：
         m ≥ -1
    From inequality(2)：
         m ≤ 2

---

    From inequalities (1) and (2)
         -1 ≤ m ≤ 2    (3)

---

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

---

    From inequality(1)：
         m ≥ 2

---

    The final solution set is :
         m ≥ 2
