8.6*2.7+62*14%+35*0.86
=0.86*27+35*0.86+62*14%
=0.86*(27+35)+62*0.14
=0.86*62+62*0.14
=(0.86+0.14)*62
=62
121+27+121*60+121*16+79*91+12*79
=121*(1+60+16)+79*(91+12)+27
=121*77+79*103+27
=9317+8137+27
=17481第二個不是最后答案。題目錯誤，應為121*27+121*60+121*16+79*91+12*79 =121*(27+60+16)+79*(91+12)=121*103+79*103=（121+79）*103=200*103=20600
8.6*2.7+62*14%+35*0.86 121+27+121*60+121*16+79*91+12*79
8.6*2.7+62*14%+35*0.86 121+27+121*60+121*16+79*91+12*79
