那位高手,给个初一上册数学题啊!就是有理数的乘除之前的,给一些吧!作业要自编试卷啊!什么题都行!
展开全部
试卷一①.(-0.8)+1.3+(-0.6)+(-2.2)+0.8+3.7
②a-b的绝对值加b+2的绝对值加c的绝对值,求a、b、c的值
③(-3)x5
④(1) 一个有理数与它的相反数的积 ( ).
(A) 是正数 (B) 是负数
(C) 一定不大于0 (D) 一定不小于0
(2) 下列说法中正确的是 ( ).
(A) 同号两数相乘,符号不变.
(B) 异号两数相乘,取绝对值较大的因数的符号.
(C) 两数相乘,积为正数,那么这两个数都为正数.
(D) 两数相乘,积为负数,那么这两个数异号.
(3)两个有理数,它们的和为正数,积也为正数,那么这两个有理数 ( )
(A)都是正数 (B)都是负数
(C)一正一负 (D)符号不能确定
(4)如果两个有理数的积小于零,和大于零,那么这两个有理数 ( )
(A)符号相反 (B)符号相反且绝对值相等
(C)符号相反且负数的绝对值大 (D)符号相反且正数的绝对值大
⑤计算下列各题:
(1) (-4) × (-7) (2)6 × (-8)
(3) (4)(-25)× 16
(5) 3 ×(-5)×(-7)× 4 (6)15 ×(-17)×(-19)×0
⑥3、初一年级共100名学生,在一次数学测试中以90分为标准,超过的记为正,不足的记为负,成绩如下:
人数 10 20 5 14 12 18 10 4 9 6 2
成绩 -1 +3 -2 +1 +10 +2 0 -7 +7 -9 -12
请你算出这次考试的平均成绩。
