25×37简便计算

简便计算 25×37+75×21 =25×(37+3×21) =25×100 =2500

25x37 =25x36 +25 =(25x4)x9 +25 =100x9+25 =900+25 =925

25×37+37×11-36×27 =(25+11)×37-36×27 =36×37-36×27 =36×(37-27) =36×10 =360

=25×(4×9+1)+17×2×(25+3) =25×4×9+25×1+17×2×25+17×2×3 =100×9+25+17×50+17×6 =900+25+850+102 =1877

原式 =(36+1)x25 =36x25+1x25 =9x4x25+25 =9x100+25 =900+25 =925 供参考。

630×25+250×37 =630X25+25X370 =(630+370)X25 =1000X25 =25000

37×25×40 =37×(25×40) =37x100 =3700

=25×4×37=100×7=3700

25×37-25×33 =25×(37-33) =25×4 =100

4×(25×37) =4×25×37 =100×37 =3700 您好,本题已解答,如果满意, 请点右上角“采纳答案”。
