Answer 1

(12/-1)+(3*12)
(12*-1)+(3*12)
(12/-1)+(12*3)
(12*-1)+(12*3)
(12*3)+(-1*12)
(12-(3*12))/-1
(12-(3*12))*-1
(12*3)+(12/-1)
(12*3)+(12*-1)
(12-(12*3))/-1
(12-(12*3))*-1
-1*(12-(3*12))
(-1*12)+(3*12)
-1*(12-(12*3))
(-1*12)+(12*3)
-1*(12-(12*3))
(-1*12)+(12*3)
-1*(12-(3*12))
(-1*12)+(3*12)
(3*12)+(-1*12)
(3*12)+(12/-1)
(3*12)+(12*-1)
(3*12)+(12/-1)
(3*12)+(12*-1)
(3*12)+(-1*12)
(12-(12*3))/-1
(12-(12*3))*-1
(12/-1)+(12*3)
(12*-1)+(12*3)
(12/-1)+(3*12)
(12*-1)+(3*12)
(12-(3*12))/-1
(12-(3*12))*-1
(12*3)+(12/-1)
(12*3)+(12*-1)
(12*3)+(-1*12)

Answer 2

12*3-（-1*-12）=24

Answer 3

-12*【-1】*3-12

Answer 4

｛-12*【（-1）*3】｝—12
