3.14*13.14*03.14*0.53.14*0.253.14*0.33.14*103.14*53.14*123.14*1.23.14*0.4除法有3.14÷10÷3.146.28÷3.143.14÷1031.4÷3.1462.8÷3.143.14÷23.14÷53.14÷0.4314÷3.14

1 * 3.14 + 9 * 3.14 = (1+9) * 3.142 * 3.14 + 8 * 3.14 = (2+8) * 3.143 * 3.14 + 7 * 3.14 = (3+7) * 3.144 * 3.14 + 6 * 3.14 = (4+6) * 3.145 * 3.14 + 5 * 3.14 = (5+5) * 3.14

3.14x1=3.14 3.14x2=6.28 3.14x3=9.42 3.14x4=12.56 3.14x5=15.7 3.14x6=18.84 3.14x7=21.98 3.14x8=25.12 3.14x9=28.26

: 3.14*(10+0.1) =3.14*10+3.14*0.1 =31.4+0.314 =31.714

10 *3.14= 31.411 *3.14= 34.5412 *3.14= 37.6813 *3.14= 40.8214 *3.14= 43.9615 *3.14= 47.116 *3.14= 50.2417 *3.14= 53.3818 *3.14= 56.5219 *3.14= 59.6620 *3.14= 62.821 *3.14= 65.9422 *3.14= 69.0823 *3.14= 72.2224 *3.14= 75.3625

3.14*任何数怎样计算简便 解答:3.14参与的计算 建议把后面的数拆开,然后用乘法分配律来做3.14*1=3.14 .3.14*10=31.4 熟记这些,比较简便哈

1570÷3.14=500,1727÷3.14=550,1884÷3.14=600,2041÷3.14=650,2198÷3.14=700 ……

(1)(3.14-π)0-(1 2 )-2+|3- 2 |=1-4+3- 2 =- 2 ;(2)(1+1 a?1 )÷(1+1 a2?1 )=a a?1 ?a2?1 a2 =a+1 a 故答案为- 2 、a+1 a .

3.14*1.5=4.710 3 . 1 4 *) 1. 5-------------------- 1 5 7 0 3 1 4------------------- 4 7 1 0

3.14除以102竖式计算3.14÷102=0.03 竖式计算过程如下图:
