〖1/1算式〗
    作业：求算式 64.559/2×(4.6-(-0.651))+(47.539+90.836)/2×(8.5-4.6) 的值.
    题型：数学计算
    解:
          64.559/2×(4.6-(-0.651))+(47.539+90.836)/2×(8.5-4.6)
        =64.559/2×(4.6-(-0.651))+(47.539+90.836)/2×(8.5-4.6)
        =64.559/2×5.251+(47.539+90.836)/2×(8.5-4.6)
        =64.559/2×5.251+138.375/2×(8.5-4.6)
        =64.559/2×5.251+138.375/2×3.9
        =32.2795×5.251+138.375/2×3.9
        =169.499654+138.375/2×3.9
        =169.499654+69.1875×3.9
        =169.499654+269.83125
        =439.330904
    答案:64.559/2×(4.6-(-0.651))+(47.539+90.836)/2×(8.5-4.6)=439.330904
