25.4乘44加2.54乘5.5加25.4怎么算（脱式）

25.4*44+2.54*5.5+25.4
=25.4*44+25.4*0.55+25.4*1
=25.4*(44+0.55+1)
=25.4*45.55
=1156.97

感觉题目可能错了，是不是应该这样：
25.4乘44加2.54乘550加25.4怎么算
25.4*44+2.54*550+25.4
=25.4*(44+55+1)
=2540

25.4乘44加2.54乘5.5加25.4

=25.4*44+25.4*0.55+25.4

=25.4*[44+0.55+1]

=25.4*45.55

=1156.97

25.4*44+2.54*5.5+25.4
=(25+0.4)*44+(25+0.4)*0.55+(25+0.4)
=1100+0.4*44+0.22+25*0.55+25+0.4
=1100+0.4*(44+1)+25*(0.55+1)+0.22
=1100+18+38.75+0.22
=1156.97

写错题了吧！
