7+57+85+68+58=多少?

应该是等于275

59*7/58+57*5/58 =(58+1)*7/58+(58-1)*5/58 =58*7/58+1*7/58+58*5/58-1*5/58 =7+7/58+5-5/58 =12+2/58 =12+1/29

59*7/58+57*5/58 =(58+1)*7/58+(58-1)*5/58 =7+7/58+5-5/58 =12+1/29 =12又1/29

58X67+58+32+58 =58X(67+1+1+1)-26 =58X70-26 =4060-26 =4034

解: 7.58亿=758000000 7.58亿除以57 =758000000÷57 ≈13298245.614 =1329.8245614万 7.58亿除以57约等于1329.8245614万

怎么用简便算法? 7/5×8/7×21/16 =8/5×21/16 =21/10

1+2-3+4+5-6+7+8-9+。。。。。+58+59-60 =0+3+6+。。。。。+57 =(0+57)x20/2 =570.

这个应该是狮子号+豹子号,市场参考价大概380元左右。
