100个计算题
100个计算题一、整数运算1. 计算：12 + 34 - 5- 解析：按照从左到右的顺序依次计算。
先算12 + 34 = 46，再算46-5 = 41。
2. 计算：25×(4 + 8)- 解析：根据乘法分配律a×(b + c)=a× b+a× c，这里a = 25，b = 4，c = 8。
所以25×4+25×8 = 100 + 200=300。
3. 计算：120÷(3×5)- 解析：先算括号里的乘法3×5 = 15，再算除法120÷15 = 8。
二、小数运算4. 计算：3.5+2.7 - 1.8- 解析：按照从左到右的顺序计算。
3.5+2.7 = 6.2，6.2 - 1.8 = 4.4。
5. 计算：2.5×(1.2 + 0.8)- 解析：先算括号里的1.2+0.8 = 2，再算乘法2.5×2 = 5。
6. 计算：1.5÷0.3 - 0.5- 解析：先算除法1.5÷0.3 = 5，再算减法5 - 0.5 = 4.5。
三、分数运算7. 计算：(1)/(2)+(1)/(3)- 解析：先通分，分母2和3的最小公倍数是6。
(1)/(2)=(3)/(6)，(1)/(3)=(2)/(6)，所以(3)/(6)+(2)/(6)=(5)/(6)。
8. 计算：(3)/(4)-(1)/(2)- 解析：先把(1)/(2)化为(2)/(4)，然后(3)/(4)-(2)/(4)=(1)/(4)。
9. 计算：(2)/(3)×(3)/(4)- 解析：分子乘分子，分母乘分母，即(2×3)/(3×4)=(6)/(12)=(1)/(2)。
四、简易方程10. 解方程：2x+3 = 7- 解析：首先方程两边同时减3，得到2x=7 - 3=4，然后两边同时除以2，x = 4÷2 = 2。
