4.9x6.27+49x0.073-0.49
=4.9x6.27+4.9x0.73-0.49
=4.9x(6.27+0.73)-0.49
=4.9x7-0.49
=34.3-0.49
=33.81
=4.9x6.27+4.9x0.73-0.49
=4.9x(6.27+0.73)-0.49
=4.9x7-0.49
=34.3-0.49

简便计算如下:
4.9×6.27+49×0.073-0.49
=4.9×6.27+4.9×0.73-0.49
=4.9×(6.27+0.73)-0.49
=4.9×7-0.49
=34.3-0.49
=33.81
4.9×6.27+49×0.073-0.49
=4.9×6.27+4.9×0.73-0.49
=4.9×(6.27+0.73)-0.49
=4.9×7-0.49
=34.3-0.49
