325x113325x113简便方法

=325X(113-12) =325X101 =325X(100+1) =325X100+325X1 =32500+325 =32825

325x(113-13)=325x100=32500

325乘113减325乘13托是简便计算方法325乘113减325乘13=325*(113-13)=325*100=32500

325÷325*113*13=(100+13)*13=1300+169=1469

325*113-325*13=325*(113-13)=325*100 =32500

=(325+19)*40=325*40+19*40=13000+760=13760

=325*4*8=1300*8=10400

=3.25x113-3.25x11300=3.25x(113-11300)=3.25x-11187=-36357.75或者=113x(3.25-325)=113x-321.75=-36357.75

解:325*113-325*13-28*18-8*28等于( 31772 ) ∵已知需求出325*113-325*13-28*18-8*28等于多少 X * Y - X * Z = X * (Y - Z) ∴325 * 113 - 325 * 13 - 28 * 18 - 8 * 28 = 325 * (113 - 13)+ 28 * (-18 - 8) = 325 * 100 + 28 * (-26) = 32500 - 728 = 31772 答:325*113-325*13-28*18-8*28等于31772

你好,简便计算式如下原式=325-113+75-87 =(325+75)-(113+87) =200希望可以帮到你.
