(i) The product (-9)*(-5)*(-6)*(-3) is posetive whereas the product (-9)8(-5)*6*(-3) is negative. why?

(ii) What will be the sign of the product if we multiply together:

(a) 8 negative integers and 3 posetive integer?

(b) 5 negative integers and 4 posetive integers?

(1) The product of (-9),(-5),(-6) and (-3) is positive because the no. of negitive integers is even and the product of (-9),8,(-5),6 and (-3) is negitive because the no. of negitive integers is odd.

(2) (a) The product will be positive as the no. of negitive integers is even.

(2) (b) The product will be negitive as no. of negitive integers is odd.
