36乘98加72的简便方法

36乘98加72=36x98+36x2=36x(98+2)=36x100=3600

原式=36*98+(36*2)=36*(98+2)=3600

36*98加72简便计算=36x100-2x36+72=3600+72-72=3600

(100减2)乘36加72=100乘36减(2乘36)加72=360减72加72=360

36*18*2*28+72 =72(18*28+1) =72{(20-2)*28+1} =72(560-56+1) =72*615 =(70+2)*615 =43050+1230 =44280

将72看成 2 x 36然后进行简算:98*36+72=98 x 36 + 2 x 36=(98 + 2) x 36=100 x 36=3600 希望我的回答对您有帮助,满意请采纳,谢谢.

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

98x36+72x1=98x36+36x2=(98+2)x36=100x36=3600

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

展开全部36*98+72=36*(100-2)+72=36*100-36*2+72=3600+(72-72)=3600
