25×37简便计算

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

25×37 =25x(40-3) =25x40-25x3 =1000-75 =925

37×25×40 =37×(25×40) =37x100 =3700

25×37×4×125×8 =(25×4)×(125×8)×37 =100×1000×37 =100000×37 =3700000 你好本题已解答,如果满意 请点右下角“采纳答案”。

22+25+28+31+34+37 =(22+28)+【25+(31+34)】+37 =50+【25+65】+37 =50+90+37 =140+37 =177

100-37.25-简便运算 解:采用凑整法, 原式=100-(38-0.75) =100-38+0.75 =62+0.75 =62.75

25×37×100×4 =(25×4)×(37×100) =100 ×3700 =370000 运用的是 乘法交换律 乘法交换律:是一种简算定律,在人民教育出版社小学四年级下册数学教材有涉及:在两个数的乘法运算中,在从左往右计算的顺序,两个因数相乘,交换因数的位置,积不变...

25×37-25×33 =25×(37-33) =25×4 =100

=37*4*25 =37*100 =3700

3700除以括号37×25括号用简便方法计算 3700÷(37×25) =3700÷37÷25 =100÷25 =4
