Hi i am new to brainly.

Step-by-step explanation:

So i am not TELLING the ans but here is the explanation :

( n=negativeandp=positive )

1. n*n=p   n*p=n    p*p=n    p*n=n so -10*-5= +50

2. LET's take the1st one for ex. it is +25-8-16. now add -8+-16= -24, now subtract 25 because it +25&-24= +1

the 3rd one is ame s the first one but make SURE the signs are correct

5.:

L.H.S = [(-1)*(-2)*-3

         = (+2)*-3

         = +2*-3

        = - 6

R.H.S = [(-2)*(-3)]*-1

       =  6*-1

      = -6

HOPE YOU UNDERSTAND !
