在数的运算中

有加(+)、减(-)、乘()、除()四种运算,我们在数学上又为了能更简便计算,简称称作简算,简算有以下几种(公式详见在常用特殊数的乘积、及简算公式)

加法:(加法交换律) (加法结合律)(近似数)

乘法:(乘法交换律)(乘法结合律)(乘法分配律)(乘法分配律变化式(四个))

减法:(减法的基本性质)(近似数)

除法:(除法的基本性质)(商不变的性质)

【简便计算】
简便计算是一种特殊的计算,它运用了运算定律与数字的基本性质,从而使计算简便,使一个很复杂的式子变得很容易计算出得数。
【脱式计算】
即递等式计算,需将一系列的数字逐步计算。在脱式计算中要先算乘、除法,后算加、减法。在乘除法连继计算时中,要按从左往右的顺序依次计算,在四则运算中,加法和减法叫做第一级运算,乘法和除法叫做第二级运算。
【注意事项】
在进行简便运算( 四则运算)时,应注意运算符号(乘除和加减)和大、中、小括号之间的关连。不要越级运算,以免发生运算错误。
【乘法分配律】
简便计算中最常用的方法是 乘法分配律。乘法分配律指的ax(b+c)=axb+axc其中a,b,c是任意实数。相反的,axb+axc=ax(b+c)叫做乘法分配律的逆运用(也叫提取 公约数),尤其是a与b互为补数时,这种方法更有用。

小学五年级小数脱式简便计算题带答案
小学五年级小数脱式简便计算题案例如下: 计算技巧:在两个数a、b同时乘以或者处以相同数c,然后进行加减的时候,可以先加减a、b这两个数,然后在与c进行乘除计算,如下: 0.52-0.152=(0.5-0.15)2=0.352=0.175; 0.5X2-0.15X2=(0.5-0.15)X2=0.35X2=0.7; 计算技巧:在加减乘除中非上例条件时候,即abcd四个自然数没有规律的时候,进行加减乘除,要先进行乘除(先算ab和cd),最后进行加减运算,如下: 2.8810.43-0.243.5=6.7-0.24 x3.5= 6.7-0.84=5.86; 计算技巧:在运算符号大、中、小括号与乘除加减之间,先运算大括号内小括号中的数,然后计算大括号中的数,最后在进行括号外的数的乘除加减运算,如下: 30.8[14-(9.85+1.07)]=30.8(14-10.92)=30.83.08=10; 扩展资料: 简便计算:简便计算是一种特殊的计算,它运用了运算定律与数字的基本性质,从而使计算简便,使一个很复杂的式子变得很容易计算出最终得数。 脱式计算:即递等式计算,需将一系列的数字逐步计算。在脱式计算中要先算乘、除法,后算加、减法。在乘除法连继计算时中,要按从左往右的顺序依次计算,在四则运算中,加法和减法叫做第一级运算,乘法和除法叫做第二级运算。 乘法分配律:简便计算中最常用的方法是乘法分配律。乘法分配律指的ax(b+c)=axb+axc其中a、b、c是任意实数。相反的,axb+axc=ax(b+c)叫做乘法分配律的逆运用(也叫提取公约数),尤其是a与b互为补数时,这种方法更有用。 注意事项:在进行简便运算(四则运算)时,应注意运算符号(乘除和加减)和大、中、小括号之间的关联。不要越级运算,以免发生运算错误。

=363

二、900072(1.250.78)

=9000727

=1257

=875

三、61-(1.25+2.50.7)

=61-3

=58

四、[(10-0.8)+9.85]-20.125

=19.05-20.125

=19.05-16

=3.05

12.5x32x25
=(12.5x8)x(25x4)
=100x100
=10000
101x54
=(100+1)x54
=100x54+54x1
=5454
8.56x99
=8.56x(100-1)
=8.56x100-1x8.56
=856-8.56
=856.35
脱式计算,即递等式计算,需将一系列的数字逐步计算。在脱式计算中要先算乘、除法,后算加、减法。在乘除法连继计算时中,要按从左往右的顺序依次计算,在四则运算中,加法和减法叫做第一级运算,乘法和除法叫做第二级运算。
2、主要掌握的是记住要先算乘、除法,后算加、减法。在乘除法连继计算时中,要按从左往右的顺序依次计算。遇到括号,要首先计算括号内部。
3、在脱式过程中要按运算顺序划出运算顺序线,还要做到“三核对”,一要核对从书上把题抄到作业本上数字、符号是否抄对。二要核对从横式抄到草稿竖式的数字、符号是否抄对。三要核对把草稿竖式上的得数,抄到横式上是否抄对,小数点是否点对地方,有无遗漏。

1、脱式计算,即递等式计算,需将一系列的数字逐步计算。在脱式计算中要先算乘、除法,后算加、减法。在乘除法连继计算时中,要按从左往右的顺序依次计算,在四则运算中,加法和减法叫做第一级运算,乘法和除法叫做第二级运算。
(31.8+3.24)5
=(31.8+12.8)5

=44.65
=8,92,

31.54(6+3)
=31.549
=1269
=14.

0.64257.8+2.2
=124.8+2.2
=127.
1、0.2008+2.008+20.08+200.8+2008
=0.2008(1+10+100+1000+10000)
=0.200811110
=2230.888
2、1(23)(34)(45)(56)……(20072008)=13/24/35/46/5……2008/2007
=2008
3、1+1/3+1/6+1/10+……+1/20091004
=2(1/2+1/6+1/12+1/20+……+1/20082009)
=2(1-1/2+1/2-1/3+1/3-1/4+……+1/2008-1/2009)
=2(1-1/2009)
=22008/2009
=4016/2009
4、2006个2006乘2007个2007再乘2008个2008的积的个位数是?
2006个2006的个位数字是6
2007个2007的个位数字是3
2008个2008的个位数字是6
636=108
所以2006个2006乘2007个2007再乘2008个2008的积的个位数字是8
5、325.24+425.24+625.24+925.24+525.24
=(300+400+600+900+500)+25.245
=2700+126.2
=2826.2
6、1/14+1/47+1/710+1/1013+……+1/20052008
=(1-1/4+1/4-1/7+1/7-1/10+1/10-1/13+……+1/2005-1/2008)3
=(1-1/2008)3
=2007/20083
=669/2008
