[1/2 Formula]
    Work: Calculate the value of equation 7777777/(3.2+3.7+0.1)-111105-0.36+(2.4+6.8)/0.5*2 .
    Question type: Mathematical calculation
    Solution:
          7777777/(3.2+3.7+0.1)-111105-0.36+(2.4+6.8)/0.5*2
        =7777777/7-111105-0.36+(2.4+6.8)/0.5*2
        =7777777/7-111105-0.36+9.2/0.5*2
        =1111111-111105-0.36+9.2/0.5*2
        =1111111-111105-0.36+18.4*2
        =1111111-111105-0.36+36.8
        =1000006-0.36+36.8
        =1000005.64+36.8
        =1000042.44
    Answer:7777777/(3.2+3.7+0.1)-111105-0.36+(2.4+6.8)/0.5*2=1000042.44
[2/2 Formula]
    Work: Calculate the value of equation 1/(0.25+0.25+0.25+0.25)+3/(0.25+0.25+0.25+0.25) .
    Question type: Mathematical calculation
    Solution:
          1/(0.25+0.25+0.25+0.25)+3/(0.25+0.25+0.25+0.25)
        =1/1+3/(0.25+0.25+0.25+0.25)
        =1/1+3/1
        =1+3/1
        =1+3
        =4
    Answer:1/(0.25+0.25+0.25+0.25)+3/(0.25+0.25+0.25+0.25)=4
