The absolute value of I9I is 9 and -9 but I would put 9 first if you can only pick one
Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.
I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...
-2/30 + -5/30 = -7/30
180-24=5
180-56=34
Both are equal
