填上适当的运算符号和小括号,使等式成立2.5 2.5 2.5 2.5=0 2.5 2.5 2.5 2.5=12.5 2.5 2.5 2.5=5 2.5 2.5 2.5 2.5=10
2.5+2.5-2.5-2.5=0
2.5÷2.5+2.5-2.5=1
2.5+2.5+2.5-2.5=5
2.5+2.5+2.5+2.5=10
2.5 - 2.5 + 2.5- 2.5=0 2.5 - 2.5 +2.5 / 2.5=1
2.5 + 2.5 + 2.5- 2.5=5 2.5 + 2.5 + 2.5 + 2.5=10
你好
1. 2.5+2.5-2.5-2.5=0
2. 2.5-2.5+2.5/2.5=1
3. 2.5+2.5+2.5-2.5=5
4. 2.5+2.5+2.5+2.5=10
2.5-2.5+2.5- 2.5=0
(2.5+2.5)/ (2.5+2.5)=1
2.5+2.5+2.5-2.5=5
2.5+2.5+2.5+2.5=10
2.5+2.5-2.5-2.5=0 2.5+2.5+2.5-2.5=5 (2.5除以2.5)乘以(2.5除以2.5)=1 2.5+2.5+2.5+2.5=10
2.5+2.5-2.5-2.5=0
2.5-2.5+2.5+2.5=5
(2.5-2.5)+2.5/2.5=1
2.5+2.5+2.5+2.5=10
2.5 ÷ 2.5 - 2.5 ÷ 2.5=0
(2.5 + 2.5 )-(2.5 +2.5)=0
(2.5+2.5)÷(2.5+2.5)=1
2.5 × 2.5 ÷ 2.5 +2.5=5
2.5 +2.5 + 2.5 + 2.5=10
