102x27-54 =100x27+2x27-54 =2700+54-54 =2700

原式等于 (100+2)×27=2754 ~回答完毕~ ~结果仅供参考~ ~\(^o^)/~祝学习进步~~~

102×27 =(100+2)x27 =100x27+2x27 =2700+54 =2754 谢谢,请采纳

100*27+2*27=2700+54=2754

用简便方法计算27×102 27×102 =27*100+27*2 =2700+54 =2754

=13×(100+2)×3×9 =39×9×(100+2) =39×(10-1)×(100+2) =(39×10-39×1)×(100+2) =351×100-351×2 =35100-702 =34398

50×102-2835÷27+5005 =50x(100+2)-2835÷9÷3+5005 =50x100+50x2-315÷3+5005 =5000+100-105+5000+5 =5000+5000+(5+100-105) =10000+0 =10000

5.27x102的简便算法 5.27x102 =5.27×(100+2) =5.27×100+5.27×2 =527+10.54 =537.54

128-27-73 =128-(27+73) =128-100 =28 102*35 =(100+2)×35 =100×35+2×35 =3500+70 =3570 (125*11)*8 =125×8×11 =1000×11 =11000 21*79+79*79 =79×(21+79) =79×100 =7900 103*48-48*3 =48×(103-3) =48×100 =4800 8*(125+9) =125×8+9×...
