b.
Write a rule for the sign of the product of more than two negative integers
b.
Explanation of Solution
The rule for the sign of the product of more than two negative integers is described below:
If the numbers of negative integers in the expression are odd then the sign of the product will be negative. And, if the numbers of negative integers are even then the sign will be positive.
c.
Suppose that in part (b) the product included positive integer factor as well. Would your rule change? Explain.
c.
Explanation of Solution
No the rule would not change if the product included positive integer factors as well.
If the numbers of negative integers in an expression are odd then the product will be negative even if it contains positive integers in it and vice-versa.
