Add appropriate operation symbols between the numbers 1.2.3.4.5.6.7.8 to get 1 1（）2（）3（）4（）5（）6（）7（）8=1

1 + 2 * 3-4 + 5-6 + 7-8 = 1, you should use your brain more embarrassed

There are also 5 5 5 = 12 7 7 7 7 = 12 8 8 8 = 12, adding operation symbols and brackets between the numbers to make the equation hold
It's right that five five are equal to 12. There are also five seven and five eight. How can the formula be equal to 12?

7+7-【(7+7)÷7】=12
8+8÷【（8+8）÷8】=12

Five five make up 12, five six make up 12, five seven make up 12, five eight make up 12
Here are four topics.

5+5+(5+5)÷5=12
(6-6)*6+6+6=12
7+7-（7+7）÷7=12
8+8÷{（8+8）÷8}=12

1 / 2 1 / 4 1 / 8 1 / 16 how to add operation symbols and brackets equal to 0, 1, 2, 4, 8, 16, 32

（1/2*1/4-1/8)*(1/16)=0
1/2*(1/4-1/8)/(1/16)=1
(1/2*1/4)/(1/8-1/16)=2
(1/2*1/4+1/8)/(1/16)=4
(1/2)/(1/4-1/8-1/16)=8
(1/2*1/4)/(1/8)/(1/16)=16
(1/2-1/4)/(1/8)/(1/16)=32
In fact, there should be many combinations to get the results, such as:
（1/2）/（1/4*1/8）/（1/16）=1
I won't say too much!
