Answer 2

Answer:

The Product of Twenty-Two negative integers and Five positive integers are positive
The Product of 139 negative integers and Twenty-Four positive integers are negative.

Step-by-step explanation:

We know,
If there is negative integers of a product is even, then the product is a positive integer and if the number of negative integers in a product is odd, then the product is a negative integer

And, if any number of positive integers will always give a positive integer.

(i) 22 negative integers and 5 positive integers: So as we can see there is Even number of negative integers, hence product is positive.

(ii) 139 negative integers and 24 positive integers: So as we can see there is Odd number of negative integers, hence product is negative.
