[ 1/5Inequality]
    Assignment:Find the solution set of inequality 24 >3x/e .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        24 >3 * x / e         (1)

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

    The final solution set is :

         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

[3/5 Formula]
    Work: Calculate the value of equation 1/2+3/4+7/8+15/16 .
    Question type: Mathematical calculation
    Solution:
          1/2+3/4+7/8+15/16
        =0.5+3/4+7/8+15/16
        =0.5+0.75+7/8+15/16
        =0.5+0.75+0.875+15/16
        =0.5+0.75+0.875+0.9375
        =1.25+0.875+0.9375
        =2.125+0.9375
        =3.0625

    Answer:1/2+3/4+7/8+15/16=3.0625
[4/5 Digtal analysis]
    Work:Break 14125 into prime factors.
    Question type: Resolving prime factor
    Solution:
        14125=5*5*5*113

    *Note: 14125 has 4 prime factors.
[5/5 Formula]
    Work: Calculate the value of equation 132+1234*24/124 .
    Question type: Mathematical calculation
    Solution:
          132+1234*24/124
        =132+29616/124
        =132+238.83871
        =370.83871

    Answer:132+1234*24/124=370.83871
