100*79+184*21+84*29100*79+184*21+84*29100*79+184*21+84*29100*79+184*21+84*29=100*79+(100+84)*21+84*2
100*79+184*21+84*29
100*79+184*21+84*29
100*79+184*21+84*29
100*79+184*21+84*29
=100*79+(100+84)*21+84*29
=100*79+100*21+84*21+84*29
=100*(21+79)+84*(21+29)
=100*100+84*50
=10000+4200
=14200
100*79+184*21+84*29
=100*79+(100+84)*21+84*29
=(100*79+100*21)+(84*21+84*29)
=100*(79+21)+84*(21+29)
=100*100+84*50
=14200
14200 是否需要简便计算？
