Consider the first row: $(-14*-8)-(-4*-16)=48$

I dont know if that would work because you are essentially cahnging the sign when you use dist. property with the -(-4 * -16). I will ask my teacher though, becaus i see what you're saying that the - 4 *-16 would be positive. I need at least 6 answers and i just hate these kind of puzzles.

Bottom row: (- 11 + 12 + 7) * 6 = 48

oh wait i just realized something. you cant subtract the positive product of $(-4 * -16)$

$5 \times 9 + 15 - 12 = 48$

I'm not sure if it works though ... (sign rules are not quite clear)

you cant subtract the positive 12. you have to take the number as is.

Well then I have no idea (Worried)
Maybe you could actually write some code to test each combination and get max results, shouldn't be that long since you only got 16 cells ?
