[1/4 Formula]
    Work: Calculate the value of equation 0.2*(0.28+0.92+0.4+0.08)*(4.2-0.12) .
    Question type: Mathematical calculation
    Solution:
          0.2*(0.28+0.92+0.4+0.08)*(4.2-0.12)
        =0.2*1.68*(4.2-0.12)
        =0.2*1.68*4.08
        =0.336*4.08
        =1.37088
    Answer:0.2*(0.28+0.92+0.4+0.08)*(4.2-0.12)=1.37088
[2/4 Formula]
    Work: Calculate the value of equation 0.2*(0.4+0.92+0.28+0.3)*(0.9-0.1) .
    Question type: Mathematical calculation
    Solution:
          0.2*(0.4+0.92+0.28+0.3)*(0.9-0.1)
        =0.2*1.9*(0.9-0.1)
        =0.2*1.9*0.8
        =0.38*0.8
        =0.304
    Answer:0.2*(0.4+0.92+0.28+0.3)*(0.9-0.1)=0.304
[3/4 Formula]
    Work: Calculate the value of equation 0.2*(0.4+0.92+0.28+0.09)*(4.2-0.12) .
    Question type: Mathematical calculation
    Solution:
          0.2*(0.4+0.92+0.28+0.09)*(4.2-0.12)
        =0.2*1.69*(4.2-0.12)
        =0.2*1.69*4.08
        =0.338*4.08
        =1.37904
    Answer:0.2*(0.4+0.92+0.28+0.09)*(4.2-0.12)=1.37904
[4/4 Formula]
    Work: Calculate the value of equation 0.2*(0.4+0.92+0.28+0.09)*(3.3-0.1) .
    Question type: Mathematical calculation
    Solution:
          0.2*(0.4+0.92+0.28+0.09)*(3.3-0.1)
        =0.2*1.69*(3.3-0.1)
        =0.2*1.69*3.2
        =0.338*3.2
        =1.0816
    Answer:0.2*(0.4+0.92+0.28+0.09)*(3.3-0.1)=1.0816
