如题所述
最右边41应该是43吧，不然哪来什么简便运算。直接算就好了。我这里就按43来算。
430×4-43+61×43
=43x39+61x43
=43x100
=4300
430×4-43+61×43
=43x39+61x43
=43x100
=4300

简便计算过程方法如下
解:430×4-43+61×41
=43×10×4+43×61×41
=43×40-43+61×41
=43×(40-1)+61×41
=43×39+61×41
=(41+2)×39+61×41
=41×39+2×39+61×41
=41×39+61×41+2×39
=41×(39+61)+78
=41×100+78
=4100+78

430*4=43*40
43*40-43+61*41
=43*(40-1)+61*41
=43*39+61*41
=(41+2)*39+61*41
=41*39+2*39+61*41
=41*39+61*41+2*39
=41*(39+61)+78
=41*100+78
=4100+78
=4178
43*40-43+61*41
=43*(40-1)+61*41
=43*39+61*41
=(41+2)*39+61*41
=41*39+2*39+61*41
=41*39+61*41+2*39
=41*(39+61)+78
=41*100+78
=4100+78
=4178
