简便运算方法如下：
47×29+53×27
=47×27+47×2+53×27
=（47+53）×27+47×2
=100×27+47×2
=2700+94
=2794
47x29+53x27
=47X（27+2）+53x27
=27x（47x2+53）
=27x147
=3969
=47×29+53×29-53×2
=29×（47+53）-106
=29×100-106
=2900-106
=2794
原式=（53-6）x29+53x27
=53（29+27）-29x6
=53x56-30x6+30
=50x56+3x56-180+30
=2800+168-150
=2818
=47x(27+2)+53x27
=47x27+47x2+53x27
=47x27+53x27+(50-3)x2
=(47+53)x27+50x2-3x2
=100x27+100-6
=2700+94
=2794
