907乘99+907=要简算和过程
简算907×99+907 我要过程,快 -
=907x(99+1)907x100 =90700
907*99+907=907*(99+1)=907*100=90700 56*99=56*(100-1)=56*100-56=5600-56=5544 4.05-2.8-0.7=4.05-(2.8+0.7)=4.05-3.5=0.55,7,简算:41乘101,907乘99加907,56乘99,4.05减2.8减0.简便运算,
=907x(99+1)907x100 =90700
907*99+907=907*(99+1)=907*100=90700 56*99=56*(100-1)=56*100-56=5600-56=5544 4.05-2.8-0.7=4.05-(2.8+0.7)=4.05-3.5=0.55,7,简算:41乘101,907乘99加907,56乘99,4.05减2.8减0.简便运算,
907x99+907 =907x(99+1)907x100 =90700 101x92-92 =92x(101-1)92x100 =9200 4.05-2.8-0.7 =4.05-(2.8+0.7)4.05-3.5 =0.55 答题不易,望采纳!
