75*26+26*25怎么简便

226-25-75-26 =(226-26)-(25+75) =200-100 =100

25+75=100 26+74=100 25到75一共有51个数 所以有25对这样的组合加最中间的一个数50 所以结果是25×100+50=2550

简便运算:75×16+25×26 75×16+25×26 =75*16+25*16+25*10 =16*(75+25)+250 =1600+250 =1850

=43x(75+26-1) =43x100=4300

(23 +26)x25 =25*(50-1) =25*50-25*1 =1250-25 =1225 75+76*25 =25*3+76*25 =25*(3+76) =25*(80-1) =25*80-25*1 =2000-25 =1975

提示:方法不唯一,如 75×2×13+150×37 =150×13+150×37 =150×(13+37) =150×50 =7500 或 75×26+75×2×37 =75×26+75×74 =75×(26+74) =75×100 =7500 希望对你有帮助!

=(-75-25/26)÷5 =(-75÷5)+(-25/26÷5) =(-15)+(-5/26) =-15又26分之5

26✘(81-75-1)=25✘5=130

75*3/4+0.75*26-3/4简便方法怎么做 =75×3/4+3/4×26-3/4 =3/4×(75+26-1) =3/4×100 =3×25 =75

2.08*75-26.8 =2*75+0.08*75-26.8 =150+6-26.8 =156-26.8 =129.2
