第二章 有理数

1 、正数与负数

在以前学过的0以外的数前面加上负号“—”的数叫负数。

与负数具有相反意义,即以前学过的0以外的数叫做正数(根据需要,有时在正数前面也加上“+”)。

2 、有理数

(1) 正整数、0、负整数统称 ,正分数和负分数统称 。

整数和分数统称 。0既不是 数,也不是 数。

(2) 通常用一条直线上的点表示数,这条直线叫数轴。

数轴三要素:原点、、单位长度。

在直线上任取一个点表示数0,这个点叫做 。

(3) 只有符号不同的两个数叫做互为相反数。

例:2的相反数是 ;-2的相反数是 ;0的相反数是

(4) 数轴上表示数a的点与原点的距离叫做数a的绝对值,记作|a|。

一个正数的绝对值是它本身;一个负数的绝对值是它的相反数;0的绝对值是0。两个负数,绝对值大的反而小。

3 、有理数的加减法

(1)有理数加法法则:

①同号两数相加,取相同的 ,并把绝对值 相加。

②绝对值不相等的异号两数相加,取 符号,并用 减去较小的绝对值。

互为相反数的两个数相加和为0。

相似变换

※1、如果选用同一个长度单位量得两条线段AB,CD的长度分别是m、n,那么就说这两条线段的比AB:CD=m:n,或写成.

※2、四条线段a、b、c、d中,如果a与b的比等于c与d的比,即,那么这四条线段a、b、c、d叫做成比例线段,简称比例线段.

※3、注意点:

①a:b=k,说明a是b的k倍;

②由于线段a、b的长度都是正数,所以k是正数;

③比与所选线段的长度单位无关,求出时两条线段的长度单位要一致;

④除了a=b之外,a:b≠b:a,与互为倒数;

平移变换

(1)图形平移前后的形状和大小没有变化,只是位置发生变化;

(2)图形平移后,对应点连成的线段平行且相等(或在同一直线上)

(3)多次平移相当于一次平移。

(4)多次对称后的图形等于平移后的图形。

(5)平移是由方向,距离决定的。

(6)经过平移,对应线段平行(或共线)且相等,对应角相等,对应点所连接的线段平行且相等。

这种将图形上的所有点都按照某个方向作相同距离的位置移动,叫做图形的平移运动,简称为平移

相似三角形

※1、在相似多边形中,最为简简单的就是相似三角形.

※2.对应角相等、对应边成比例的三角形叫做相似三角形.相似三角形对应边的比叫做相似比.

※3、全等三角形是相似三角的特例,这时相似比等于1.注意:证两个相似三角形,与证两个全等三角形一样,应把表示对应顶点的字母写在对应的位置上.

※4、相似三角形对应高的比,对应中线的比与对应角平分线的比都等于相似比.

※5、相似三角形周长的比等于相似比.

※6、相似三角形面积的比等于相似比的平方.

统计

科学记数法:一个大于10的数可以表示成A_10N的形式,其中1小于等于A小于10,N是正整数。

扇形统计图:①用圆表示总体,圆中的各个扇形分别代表总体中的不同部分,扇形的大小反映部分占总体的百分比的大小,这样的统计图叫做扇形统计图。②扇形统计图中,每部分占总体的百分比等于该部分所对应的扇形圆心角的度数与360度的比。

各类统计图的优劣:条形统计图:能清楚表示出每个项目的具体数目;折线统计图:能清楚反映事物的变化情况;扇形统计图:能清楚地表示出各部分在总体中所占的百分比。

近似数字和有效数字:①测量的结果都是近似的。②利用四舍五入法取一个数的近似数时,四舍五入到哪一位,就说这个近似数精确到哪一位。③对于一个近似数,从左边第一个不是0的数字起,到精确到的数位止,所有的数字都叫做这个数的有效数字。

平均数:对于N个数X1,X2…XN,我们把(X1+X2+…+XN)/N叫做这个N个数的算术平均数,记为X(上边一横)。

加权平均数:一组数据里各个数据的重要程度未必相同,因而,在计算这组数据的平均数时往往给每个数据加一个权,这就是加权平均数。

中位数与众数:①N个数据按大小顺序排列,处于最中间位置的一个数据(或最中间两个数据的平均数)叫做这组数据的中位数。②一组数据中出现次数的那个数据叫做这个组数据的众数。③优劣:平均数:所有数据参加运算,能充分利用数据所提供的信息,因此在现实生活中常用,但容易受极端值影响;中位数:计算简单,受极端值影响少,但不能充分利用所有数据的信息;众数:各个数据如果重复次数大致相等时,众数往往没有特别的意义。

调查:①为了一定的目的而对考察对象进行的全面调查,称为普查,其中所要考察对象的全体称为总体,而组成总体的每一个考察对象称为个体。②从总体中抽取部分个体进行调查,这种调查称为抽样调查,其中从总体中抽取的一部分个体叫做总体的一个样本。③抽样调查只考察总体中的一小部分个体,因此他的优点是调查范围小,节省时间,人力,物力和财力,但其调查结果往往不如普查得到的结果准确。为了获得较为准确的调查结果,抽样时要主要样本的代表性和广泛性。

频数与频率:①每个对象出现的次数为频数,而每个对象出现的次数与总次数的比值为频率。②当收集的数据连续取值时,我们通常先将数据适当分组,然后再绘制频数分布直方图。

篇4:七年级上册数学复习资料

第一章 有理数

1.1 正数与负数

①正数:大于0的数叫正数。(根据需要,有时在正数前面也加上“+”)

②负数:在以前学过的0以外的数前面加上负号“—”的数叫负数。与正数具有相反意义。

③0既不是正数也不是负数。0是正数和负数的分界,是的中性数。

注意:搞清相反意义的量:南北;东西;上下;左右;上升下降;高低;增长减少等

1.2 有理数

1.有理数(1)整数:正整数、0、负整数统称整数(integer),

(2)分数;正分数和负分数统称分数(fraction)。

(3)有理数;整数和分数统称有理数(rational number). 以用m/n(其中m,n是整数,n≠0)表示有理数。

2.数轴

(1)定义 :通常用一条直线上的点表示数,这条直线叫数轴(number axis)。

(2)数轴三要素:原点、正方向、单位长度。

(3)原点:在直线上任取一个点表示数0,这个点叫做原点(origin)。

(4)数轴上的点和有理数的关系:

所有的有理数都可以用数轴上的点表示出来,但数轴上的点,不都是表示有理数。

只有符号不同的两个数叫做互为相反数(opposite number)。(例:2的相反数是-2;0的相反数是0)

数轴上表示数a的点与原点的距离叫做数a的绝对值(absolute value),记作|a|。从几何意义上讲,数的绝对值是两点间的距离。

一个正数的绝对值是它本身;一个负数的绝对值是它的相反数;0的绝对值是0。两个负数,绝对值大的反而小。

1.3 有理数的加减法

①有理数加法法则:

1.同号两数相加,取相同的符号,并把绝对值相加。

2.绝对值不相等的异号两数相加,取绝对值较大的加数的符号,并用较大的绝对值减去较小的绝对值。互为相反数的两个数相加得0。

3.一个数同0相加,仍得这个数。

加法的交换律和结合律

②有理数减法法则:减去一个数,等于加这个数的相反数。

1.4 有理数的乘除法

①有理数乘法法则:两数相乘,同号得正,异号得负,并把绝对值相乘。任何数同0相乘,都得0。

乘积是1的两个数互为倒数。乘法交换律/结合律/分配律

②有理数除法法则:除以一个不等于0的数,等于乘这个数的倒数。

两数相除,同号得正,异号得负,并把绝对值相除。

0除以任何一个不等于0的数,都得0。

1.5 有理数的乘方

求n个相同因数的积的运算,叫乘方,乘方的结果叫幂(power)。在a的n次方中,a叫做底数(base number),n叫做指数(exponent)。负数的奇次幂是负数,负数的偶次幂是正数。正数的任何次幂都是正数,0的任何次幂都是0。

有理数的混合运算法则:先乘方,再乘除,最后加减;同级运算,从左到右进行;如有括号,先做括号内的运算,按小括号、中括号、大括号依次进行。

把一个大于10的数表示成a×10的n次方的形式,使用的就是科学计数法,注意a的范围为1≤a <10。

从一个数的左边第一个非0数字起,到末位数字止,所有数字都是这个数的有效数字(significant digit)。四舍五入遵从精确到哪一位就从这一位的下一位开始,而不是从数字的末尾往前四舍五入。比如:3.5449精确到0.01就是3.54而不是3.55.

第二章 整式的加减

2.1 整式

单项式:由数字和字母乘积组成的式子。系数,单项式的次数. 单项式指的是数或字母的积的代数式.单独一个数或一个字母也是单项式.因此,判断代数式是否是单项式,关键要看代数式中数与字母是否是乘积关系,即分母中不含有字母,若式子中含有加、减运算关系,其也不是单项式.

单项式的系数:是指单项式中的数字因数;

单项数的次数:是指单项式中所有字母的指数的和.

多项式:几个单项式的和。判断代数式是否是多项式,关键要看代数式中的每一项是否是单项式.每个单项式称项,常数项,多项式的次数就是多项式中次数的次数。多项式的次数是指多项式里次数项的次数,这里 是次数项,其次数是6;多项式的项是指在多项式中,每一个单项式.特别注意多项式的项包括它前面的性质符号.

它们都是用字母表示数或列式表示数量关系。注意单项式和多项式的每一项都包括它前面的符号。

单项式和多项式统称为整式。

2.2整式的加减

同类项:所含字母相同,并且相同字母的指数也相同的项。与字母前面的系数(≠0)无关。

同类项必须同时满足两个条件:(1)所含字母相同;(2)相同字母的次数相同,二者缺一不可.同类项与系数大小、字母的排列顺序无关

合并同类项:把多项式中的同类项合并成一项。可以运用交换律,结合律和分配律。

合并同类项法则:

合并同类项后,所得项的系数是合并前各同类项的系数的和,且字母部分不变;

字母的升降幂排列:按某个字母的指数从小(大)到大(小)的顺序排列。

如果括号外的因数是正(负)数,去括号后原括号内各项的符号与原来的符号相同(反)。

整式加减的一般步骤:

1、如果遇到括号按去括号法则先去括号. 2、结合同类项. 3、合并同类项

2.3整式的乘法法则 :

单项式与单项式相乘,把它们的系数、同底数幂分别相乘,其余字母连同它的指数不变,作为积的因式 ;

单项式和多项式相乘,就是用单项式去乘多项式的每项,再把所得的积相加。

多项式和多项式相乘,先用一个多项式的每一项乘另一个多项式的每一项,再把所得的积相加。

2.4整式的除法法则

单项式相除,把系数、同底数幂分别相除,作为商的因式,对于只在被除式里含有的字母,则连同它的指数作为商的一个因式。

多项式除以单项式,先把这个多项式的每一项除以这个单项式,再把所得的商相加。
