[1/3 Formula]
    Work: Calculate the value of equation 0.08+(3.2+1.5)*7.3+0.05*0.4-0.002 .
    Question type: Mathematical calculation
    Solution:
          0.08+(3.2+1.5)*7.3+0.05*0.4-0.002
        =0.08+4.7*7.3+0.05*0.4-0.002
        =0.08+34.31+0.05*0.4-0.002
        =0.08+34.31+0.02-0.002
        =34.39+0.02-0.002
        =34.41-0.002
        =34.408
    Answer:0.08+(3.2+1.5)*7.3+0.05*0.4-0.002=34.408
[2/3 Formula]
    Work: Calculate the value of equation 8/(3.21+0.79)+10/(4.23+0.77) .
    Question type: Mathematical calculation
    Solution:
          8/(3.21+0.79)+10/(4.23+0.77)
        =8/4+10/(4.23+0.77)
        =8/4+10/5
        =2+10/5
        =2+2
        =4
    Answer:8/(3.21+0.79)+10/(4.23+0.77)=4
[3/3 Formula]
    Work: Calculate the value of equation 1+1.2+1.23+1.234+1.2345+1.23456+1.234567 .
    Question type: Mathematical calculation
    Solution:
          1+1.2+1.23+1.234+1.2345+1.23456+1.234567
        =2.2+1.23+1.234+1.2345+1.23456+1.234567
        =3.43+1.234+1.2345+1.23456+1.234567
        =4.664+1.2345+1.23456+1.234567
        =5.8985+1.23456+1.234567
        =7.13306+1.234567
        =8.367627
    Answer:1+1.2+1.23+1.234+1.2345+1.23456+1.234567=8.367627
