Answer 1

I think you have to do step by step and so you have the input and output chart so 32 | 20 find out the pattern its going by like what  +,/,*,- would get you to 20 the best I can help

Answer 2

32 minus 12 equals 20.                     (32)minus 12= (20)
14 minus 12 equals 2                        (14)minus 12= (2)
-6 plus 12 equals -6                           (-6) minus 12= (-6)
-2 minus 12 equals -14                      (-2) minus 12= (-14)
-10 minus 12 equals -2                      (-10)minus 12= (-2)
