Thank You.
If (-1)*(-1) will equal -1, then...
Someone can't subtract numbers. 9 - 3 - 3 - 1 = 2 Also (3-1)*(3-1)=9-3-3+1=4 Have you finished 1st grade?

Then plugging either +/-2 in any of your equation you will find the gap.

You messed up.
If (-1)*(-1)=-1
Then (3-1)(3-1) will equal 9-3-3 and then...
It would equal -1...if (-1)(-1) equals 1 as I have stated.
Though I did make a with the initial arithmetic.
(3-1)*(3-1) will equal 9-3-3-1=2 and not 4, which (3-1)*(3-1)=(2)*(2) is!
