Second, we should adhere to three on the economic benefits of improving, outreach 初一数学上册复习教学知识点归纳总结一:有理数概念、定义：1、大于 0 的数叫做正数。2、在正数前面加上负号“-”的数叫做负数。3、整数和分数统称为有理数。4、人们通常用一条直线上的点表示数，这条直线叫做数轴。5、在直线上任取一个点表示数0，这个点叫做原点。6、一般的，数轴上表示数a 的点与原点的距离叫做数a 的绝对值。7、 由绝对值的定义可知： 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。8、正数大于 0，0 大于负数，正数大于负数。9、两个负数，绝对值大的反而小。10、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负号，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。11、有理数的加法中，两个数相加，交换交换加数的位置，和不变。12、有理数的加法中，三个数相加，先把前两个数相加，或者先把后两个数相加，和不变。13、有理数减法法则减去一个数，等于加上这个数的相反数。14、有理数乘法法则两数相乘，同号得正，异号得负，并把绝对值向乘。任何数同 0 相乘，都得 0。15、有理数中仍然有：乘积是1 的两个数互为倒数。16、一般的，有理数乘法中，两个数相乘，交换因数的位置，积相等。17、 三个数相乘，先把前两个数相乘，或者先把后两个数相乘，积相等。18、 一般地，一个数同两个数的和相乘，等于把这个数分别同这两个数相乘，再把积相加。19、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。20、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。21、 求 n 个相同因数的积的运算，叫做乘方，乘方的结果叫做幂。在an 中，a叫做底数， n 叫做指数。22、根据有理数的乘法法则可以得出精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 1 页，共 4 页er eliminat.

Second, we should adhere to three on the economic benefits of improving, outreach 负数的奇次幂是负数，负数的偶次幂是正数。显然，正数的任何次幂都是正数，0 的任何次幂都是0。23、做有理数混合运算时，应注意以下运算顺序：（1）先乘方，再乘除，最后加减；（2） 同级运算，从左到右进行；（3） 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。24、把一个大于 10 数表示成 a 10n 的形式（其中 a 是整数数位只有一位的数，n 是正整数），使用的是科学计数法。25、接近实际数字，但是与实际数字还是有差别，这个数是一个近似数。26、从一个数的左边的第一个非0 数字起，到末尾数字止，所有的数字都是这个数的有效数字。二:整式的加减概念、定义：1、都是数或字母的积的式子叫做单项式（monomial ），单独的一个数或一个字母也是单项式。2、单项式中的数字因数叫做这个单项式的系数（coefficient ）。3、 一个单项式中，所有字母的指数的和叫做这个单项式的次数（degree of a monomial ）。4、几个单项的和叫做多项式（polynomial ），其中，每个单项式叫做多项式的项（term），不含字母的项叫做常数项（constantly term）。5、 多项 式里次 数 最高 项 的次数 ， 叫做 这个 多项 式的 次数（ degree of a polynomial ）。6、把多项式中的同类项合并成一项，叫做合并同类项。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。7、如果括号外的因数是正数， 去括号后原括号内各项的符号与原来的符号相同；8、如果括号外的因数是负数， 去括号后原括号内各项的符号与原来的符号相反。9、一般地，几个整式相加减，如果有括号就先去括号，然后再合并同类项。三:一元一次方程概念、定义：1、列方程时，要先设字母表示未知数，然后根据问题中的相等关系，写出还有未知数的等式方程。2、含有一个未知数（元），未知数的次数都是1，这样的方程叫做一元一次方程。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页，共 4 页er eliminat.
