2.51X48+25.1X5.3-5.3
=2.51X(48+53)-5.3
=2.51X101-5.3
=2.51X100+2.51X1-5.3
=251+2.51-5.3
=253.51-5-0.3
=248.21
=2.51X(48+53)-5.3
=2.51X101-5.3
=2.51X100+2.51X1-5.3
=251+2.51-5.3
=253.51-5-0.3
=248.21

2.51x48+25.1x5.3-5.3
=25.1x（4.8+5.3）-5.3
=25.1x10.1-5.3
=25.1x（10+0.1）-5.3
=251+2.51-5.3
=253.51-5.3
=248.21
=25.1x（4.8+5.3）-5.3
=25.1x10.1-5.3
=25.1x（10+0.1）-5.3
=251+2.51-5.3
=253.51-5.3
