1. ## Math Puzzle-I need help!

Click on the attachment(microsoft word needed). I need as many answers as i can get! Thanks!

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

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.

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

The 11 isnt negative.

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

7. $\displaystyle 5 \times 9 + 15 - 12 = 48$

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.

9. Well then I have no idea
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 ?
