有理数的加减乘除混合运算70题(4个数的)
不要乘方!70题,答案有的话更好,没有也无所谓,只要4个有理数的加减乘除!!!不要只有加减!!!!!快!!!!!呼……终于写完了,不过还是谢谢大家啦!!!...

还真是麻烦啊!
(一)计算题:
(1)23+(-73)
(2)(-84)+(-49)
(3)7+(-2.04)
(4)4.23+(-7.57)
(5)(-7/3)+(-7/6)
(6)9/4+(-3/2)
(7)3.75+(2.25)+5/4
(8)-3.75+(+5/4)+(-1.5)
(二)用简便方法计算:
(1)(-17/4)+(-10/3)+(+13/3)+(11/3)
(2)(-1.8)+(+0.2)+(-1.7)+(0.1)+(+1.8)+(+1.4)
(1)(+5)-(-3)+(-8)-(+3)+(-4)-(+5);
(2)(-6.55)+4
-(-6.55)+(-8.1)-(-8.1);
(3)|0-5|-|(-4)-(+6)|-|(-7.5)+2-(+5.5)|;
(3)(+33
)×(-0.25)×(-7)×(+4)×(-0.3);
(4)-13×125-13×216+(-13)×(-301);
[|-98|+76+(-87)]-23[56+(-75)-(7)]-(8+4+3)
-(-89)+|-87|-23+[-75-(7)+76]-(10+39-24)
|-9.8|+(-4.6)-[8.7-(-1.3)]+(-5.4)-(-0.2)
[-(-84)+46]-|-9.1|+(+1.9)
[-(-90)+(-34)]-(+43)+(-57)+10

1/2+3+5/6-7/12
[2/3-4-1/4+(-0.4)]/1/3+2
22+(-4)+(-2)+4-3
-2+8-8-1/2+8/1/8
