I don't have the options but want to know the answer
One set S contains all negative numbers, factors of 16 and another set T contains all negative numbers,factors of 8.A number x is chosen from set S and another number y is from set T.What is the least possible value of x-y?
To minimize x-y, we need to minimize x and maximize y
Minimum x we can choose is -16
Maximum y we can choose is -1
So minimum x-y is -15
