简便计算,11X11一11

11X11一11 =11×(11-1) =11×10 =110

=(11x11)(11-1)-10 =(11x11)10-10 =10(11x11-1) =1200

11x(111-11)=1100

11x11x11-11x11+11 =11X(11X11-11+1) =11X{11X(11-1)+1} =11X(11X10+1) =11X(110+1) =11X111 =1221 希望对你有帮助,满意请及时采纳, 你的采纳是我回答的动力!

11×11×11-11×11 =11×11×(11-1) =121×10 =1210

12x12十11x11一12x11一11x10 =12x12一12x11十(11x11一11x10) =12x(12一11)十11x(11一10) =12+11 =23

原式 =11/10x11/10x11/10-11/10x11/10 =11/10x11/10x11/10-11/10x11/10x1 =11/10x11/10x(11/10-1) =11/10x11/10x1/10 =(11x11)/(10x10x10) =121/1000 其中,/是分数线。 供参考。

原式 =11x11x35x2 =121x70 =8470

原式 =2/11x11x13+1/13x11x13 =(2/11x11)x13+(1/13x13)x11 =2x13+1x11 =26+11 =37 供参考。
