To state: the sign when multiplying more than two integers.

Answer to Problem 48HP
When multiplying more than two integers, if the number of negative integers are even, the sign is positive and if the negative integers are odd, the sign is negative.
Explanation of Solution
Given information:
Multiplying more than two integers.
since, the product of two same sign integers is positive,
So if the number of integers are even and all are same sign then the sign of product is positive.
If the number of integers are even and they have odd number of negative integers, the sign of the product is negative.
If the number of integers are odd and they have all negative integers, the sign of the product is negative.
If the number of integers are odd and they have even negative integers, the sign of the product is positive.
