简便算:0.37+1.37-0.37+1.37
简便算:0.37+1.37-0.37+1.37

简便算:0.37+1.37-0.37+1.37
0.37+1.37-0.37+1.37
=0.37-0.37+1.37+1.37
=1.37+1.37
=2.74

0.37+1.37-0.37+1.37
=0.37-0.37+1.37+1.37
=2.74

0.37+1.37-0.37+1.37
=1.37×2
=2.74

原式=(0.37-0.37)+(1.37+1.37)
=0+1.37*2
=2.74

0.37+1.37-0.37+1.37
=0.37-0.37+1.37x2
=2.74
