小学数学练习题括号加减混合运算
小学数学练习题括号加减混合运算1. 计算下列各题的结果：(1) 2 + (5 - 1)(2) 3 - (4 + 2)(3) (6 + 3) - 5(4) 8 - (2 - 3)(5) 4 + (7 - 3) - 2(6) (10 - 4) + (6 - 2)(7) 9 - (4 - 2) + 7(8) (5 + 3) - (2 - 1)(9) 1 + 2 - (5 - 2)(10) 5 - (2 + 1) + 4解答：(1) 2 + (5 - 1) = 2 + 4 = 6(2) 3 - (4 + 2) = 3 - 6 = -3(3) (6 + 3) - 5 = 9 - 5 = 4(4) 8 - (2 - 3) = 8 - (-1) = 9(5) 4 + (7 - 3) - 2 = 4 + 4 - 2 = 6(6) (10 - 4) + (6 - 2) = 6 + 4 = 10(7) 9 - (4 - 2) + 7 = 9 - 2 + 7 = 14(8) (5 + 3) - (2 - 1) = 8 - 1 = 7(9) 1 + 2 - (5 - 2) = 1 + 2 - 3 = 0(10) 5 - (2 + 1) + 4 = 5 - 3 + 4 = 62. 根据上述计算结果，判断下列等式的真伪：(1) 4 + (6 - 3) = (8 - 2) - 1(2) (20 - 10) + (2 - 1) = 10 - (3 + 6)(3) 3 + (8 - 5) = 6 + (2 - 1)(4) (9 - 6) + (4 - 2) = 8 - (3 - 2)(5) (15 - 5) + (3 + 2) = 5 - (4 - 1)解答：(1) 4 + (6 - 3) = 4 + 3 = 7(8 - 2) - 1 = 6 - 1 = 57 ≠ 5所以等式不成立。
(2) (20 - 10) + (2 - 1) = 10 + 1 = 1110 - (3 + 6) = 10 - 9 = 111 ≠ 1所以等式不成立。

十以内带括号加减法口算题卡
十以内带括号加减法口算题卡一、题目示例1. 加法类- （2）+3 =- 题目解析：这道题考查的是10以内的加法运算。
括号里的数是2，求2加3的结果。
我们可以通过数手指或者在脑海中想象数的累加来计算。
先数出2个物体，再接着数3个物体，总共是5个物体，所以2 + 3=5。
- 1+(4) =- 题目解析：这里1加上括号里的数4。
我们可以理解为在1的基础上再增加4个，从1开始数4个数，1、2、3、4，得到5，即1+4 = 5。
2. 减法类- （5）-2 =- 题目解析：这是10以内的减法运算。
括号里是5，意思是从5里面减去2。
我们可以用数手指的方法，伸出5个手指，然后弯下2个手指，剩下3个手指，所以5 - 2 = 3。
- 7-(3) =- 题目解析：7减去括号里的3。
可以想象有7个苹果，拿走3个，数一下剩下的苹果个数，7、6、5、4，剩下4个，所以7 - 3 = 4。
3. 混合运算类- （3）+(4 - 1)=- 题目解析：这是一道混合运算题，先算括号里的减法，4 - 1 = 3，然后再算括号外的加法，3+3 = 6。
- 8-(2 + 3)=- 题目解析：先计算括号里的加法，2+3 = 5，然后用8减去这个和，8 - 5 = 3。
二、更多题目练习1. （1）+2 =2. 3+(2) =3. （4）-1 =4. 6-(2) =5. （2）+(3 - 1)=6. 5-(1+2)=7. （3）+4 =8. 7-(4) =9. （1）+(5 - 2)=10. 9-(3+3)=。
