简便计算99乘63 63 急

63*99+63 =63(99+1) =63*100 =6300

63*99+63 =63*99+63*1=63*100=6300

99*63+36*99+99的简便运算=99*63+36*99+99x1=99x(63+36+1)=99x100=9900

99x63; =(100-1)x63; =100x63-1x63; =630-63; =567

99*63=(100-1)*63=100*63-1*63=6300-63=6237

解:运用拆分法和分配律,原式=63x99=63*(100-1)=63*100-63*1=6300-63=6237

=(99+1)*63 =100*62 =5200

63*99 =63*100-63 =6300-63 =6237

99*63+36*99+99=99*(63+36+1)=99*100=9900

解:63x99 =63x(100-1) =63x100-63x1 =6300-63 =6237
