    Work: Calculate the value of equation 90+arctan1.3-arctan130-arctan0.13-arctan(0.05*1.3) .
    Question type: Mathematical calculation
    Solution:
          90+arctan1.3-arctan130-arctan0.13-arctan(0.05*1.3)
        =90+arctan1.3-arctan130-arctan0.13-arctan0.065
        =90+0.915101-arctan130-arctan0.13-arctan0.065
        =90+0.915101-1.563104-arctan0.13-arctan0.065
        =90+0.915101-1.563104-0.129275-arctan0.065
        =90+0.915101-1.563104-0.129275-0.064909
        =90.915101-1.563104-0.129275-0.064909
        =89.351997-0.129275-0.064909
        =89.222722-0.064909
        =89.157813

    Answer:90+arctan1.3-arctan130-arctan0.13-arctan(0.05*1.3)=89.157813
