    Work: Calculate the value of equation (8.2+0.3*2+1.221*2)*(9.1+0.3*2+1.221*2)+(10.521+0.3*2+1.221*2)*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2 .
    Question type: Mathematical calculation
    Solution:
          (8.2+0.3*2+1.221*2)*(9.1+0.3*2+1.221*2)+(10.521+0.3*2+1.221*2)*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2
        =11.242*(9.1+0.3*2+1.221*2)+(10.521+0.3*2+1.221*2)*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2
        =11.242*12.142+(10.521+0.3*2+1.221*2)*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2
        =11.242*12.142+13.563*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2
        =11.242*12.142+13.563*2.2*2+37.6982*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2
        =11.242*12.142+13.563*2.2*2+37.6982*0.1+4.542*0.3+(2.028+0.3*2+1.221*2)*2*2
        =11.242*12.142+13.563*2.2*2+37.6982*0.1+4.542*0.3+5.07*2*2
        =136.500364+13.563*2.2*2+37.6982*0.1+4.542*0.3+5.07*2*2
        =136.500364+29.8386*2+37.6982*0.1+4.542*0.3+5.07*2*2
        =136.500364+59.6772+37.6982*0.1+4.542*0.3+5.07*2*2
        =136.500364+59.6772+3.76982+4.542*0.3+5.07*2*2
        =136.500364+59.6772+3.76982+1.3626+5.07*2*2
        =136.500364+59.6772+3.76982+1.3626+10.14*2
        =136.500364+59.6772+3.76982+1.3626+20.28
        =196.177564+3.76982+1.3626+20.28
        =199.947384+1.3626+20.28
        =201.309984+20.28
        =221.589984
    Answer:(8.2+0.3*2+1.221*2)*(9.1+0.3*2+1.221*2)+(10.521+0.3*2+1.221*2)*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(2.028+0.3*2+1.221*2)*2*2=221.589984
