Question

3) what will be the sign of the product if we multiply together:

a) 10 negative ok integers and 4 positive integers?

b) 5 negative integers and 7 positive integers?​

Answer 1

Answer:

b) When multiply odd number of integers we get a -'ve integer. That multiplied by 7 +'ve integers will give a negative integer.

A positive integer multiplied by a-be integer will give -'ve integer
