Add appropriate operation symbols or brackets between the following numbers 1 23 4 5 6 7 = 9

1+（2x3-4）x（5+6-7）=9
（1+2）/3+4+5+6-7=9
1*（2-3）*（4+5）*（6-7）=9
（1+2）*3*（4-5）*（6-7）=9

Add "+", "-" and other symbols in the middle of the four 1 / 2 to make them equal to 0,1,2,3,4, respectively?

1/2+1/2-1/2-1/2=0

1/2+1/2+1/2+1/2=2
(1/2+1/2+1/2)÷1/2=3
(1/2+1/2)÷(1/2*1/2)=4
