98乘以35的简便运算

九十八乘以三十五=(100-2)*35=100*35-2*35=3500-70=3430

解:98X35 =(100-2)X35 =100X35-2X35 =3500-70 =3430

98x35=100x35-2x35=3500-70=3430 谢谢,请采纳

98*35=(100-2)*35=100*35-2*35=3500-70=3430

98*35=(100-2)*35=100*35-2*35=3500-70=3430

简便计算过程方法如下 解:35x98=35x(100-2)=35x100-35x2=3500-70=3430

解:原式=35*(100-2) =35*100-35*2 =3500-70 =3430

35*98=35*(100-2)=35*100-35*2=3500-70=34309接近100,可改写成100-2.用乘法分配律进行简便.

98乘0.35的简便算法98*0.35=(100-2)*0.35=100*0.35-2*0.35=35-0.7=34.3.

36乘98+72=36乘98+36乘2=36乘(98+2)=36乘100=3600
