Using multiplication rules, it is found that the result of the multiplication will be a negative number.
<h3>What are multiplication rules?</h3>
- When two numbers of the same signal are multiplied, the result is positive.
- Hence, when an even number of negative numbers are multiplied, the result is positive. If an odd number is multiplied, the result is negative.
Hence, in this problem we have that:
- The result of the multiplication of the 13 negative integers is negative.
- The result of the multiplication of the 18 positive integers is positive.
- The multiplication of both results is the multiplication of a negative by a positive, hence it is negative.
