Question

If 9 negative integers and 3 positive integers are multiplied, then the sign of the product is
positive or negative?

Answer 1

let we can multiply it

for example

I am taking -2 and 1

-2×-2×-2×-2×-2×-2×-2×-2×-2 = -18

= 1×1×1=1

= -18×1=-18

another way is

9 is a odd number and 3 also odd number. if odd number means it's a negative sign

hence the sign of product is negative.

Answer 2

Answer:

Step-by-step explanation:

I am taking -2 and 1...

-2 x-2 x-2 x -2 x -2 x -2 x -2 x -2 x -2 = -18

1 x 1 x 1 = 1

= -18 x 1 = -18

hence the sign of product is negative.
