2.13一2.13x0.5的简便计算怎么算

2.13-2.13×0.5 =2.13×(1-0.5) =2.13×0.5 =(2.13÷2)

解: 2.65x1.7+13.5x0.17 =2.65x1.7+1.35x1.7 =(2.65+1.

这道题你在5.2和0.023中间可以丢了个加号或减号,如果按加号算简便方法应该是: 2.3X0.3

没有了吧- -一般都是十字相乘法最简单了。WW望采纳谢谢!

0.5x2.13x8 =0.5×8×2.13 =4×2.13 =8.52

0.87×3.16+4.64=7.3892。 简便计算过程如下: 方法一、 0.87×3.16+4.

详见计算器

3.14x2.6+0.186x26 =3.14x2.6+1.86x2.6 =(3.14+1.86)×

(1)2.5*32*0.125 =(2.5*4)*(8*0.125) =10*1 =10

8.7x3.6+13x0.36 =8.7x3.6+1.3x3.6 =(8.7+1.3)x3.
