36x45 36x56-36

=36x(45+56)-36=36x100-36=3600-36=3564 如果有帮到您 请好评 哦 谢谢;啊

36x45+36x56-36=36x(45+56-1)=36x100=3600

36*45+36*56-36=36x(45+56-1)=36x100=3600 亲,请【采纳答案】,您的采纳是我答题的动力,谢谢.

36*56+72*22 =36X56+36X44 =36X(56+44) =3600

36*45+36*56-36=36*45+36*56-36*1=36*(45+56-1)=36*100=3600

解:原式=56x56+56x44=56X(56+44)=56X100=5600

36*145-36*45=36*(145-45)=36*100=3600

简便计算过程方法如下解:原式=(55+45)x36=100x36=3600

提取公因式36 原式=36*(45+54+1)=36*100=3600

654-(45+36)=654-(44+37)=654-44-37=610-10-27=600-27=573
