Question

1.
What will be the sign of the product if we multiply together:
(a) 9 negative integers and 4 positive integers?​

Answer 1

Answer:

(+×+) =+

The product of 4 positive integers will be positive

(-×-) =+

The product of 8 positive integers will become positive

(+×-) = -

Positive integer multiplied by 1 negative integer becomes negative.

Therefore when 9 integers are multiplied together the product is negative

(+×-) = -

Therefore the final product will be a negative integer
