[1/1 Formula]
    Work: Calculate the value of equation 90+arctan(10)-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10) .
    Question type: Mathematical calculation
    Solution:
          90+arctan(10)-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)
        =90+arctan10-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)
        =90+arctan10-arctan1-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)
        =90+arctan10-arctan1-arctan0.2-arctan(0.01*10)-arctan(10*10)
        =90+arctan10-arctan1-arctan0.2-arctan0.1-arctan(10*10)
        =90+arctan10-arctan1-arctan0.2-arctan0.1-arctan100
        =90+1.471128-arctan1-arctan0.2-arctan0.1-arctan100
        =90+1.471128-0.785398-arctan0.2-arctan0.1-arctan100
        =90+1.471128-0.785398-0.197396-arctan0.1-arctan100
        =90+1.471128-0.785398-0.197396-0.099669-arctan100
        =90+1.471128-0.785398-0.197396-0.099669-1.560797
        =91.471128-0.785398-0.197396-0.099669-1.560797
        =90.68573-0.197396-0.099669-1.560797
        =90.488334-0.099669-1.560797
        =90.388665-1.560797
        =88.827868

    Answer:90+arctan(10)-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)=88.827868
