78x37十24x37简便计算

78x37十24x37=(78+24)x37=(100+2)x37=100x37+2x37=3700+74=3774

(1-1)78*37 =0*78*37(0乘以任何数得0) =0

78x37一37x78 解:简便计算=78x37-78x37=0 因为含有因式的减数和被减数相同,所以差是0.祝学习进步.

78x37-37x68=78x37-68x37=(78-68)x37=10x37=370

24X37+37X83-7X37=37X(24+83-7)=37X100=3700望采纳

75x37+26x37-37=37 x (75 + 26 - 1)=37 x 100=3700希望我的回答对您有帮助,满意请采纳,谢谢.
