The rule works the same way when you have more than two numbers to multiply or divide. An even number of negative numbers will give a positive answer. An odd number of negative numbers will give a negative answer.
What is the sign of a negative number?
Negative numbers are usually written with a minus sign in front. For example, −3 represents a negative quantity with a magnitude of three, and is pronounced “minus three” or “negative three”.
What is the product of an even number of negative factors?

Is the number 1 even?

What happens if you have odd number of negatives?
If you have an odd number of negative numbers in your product or in your quotient, well then you’re going to have a negative, you’re going to have a negative value for the entire expression. If you have an even, if you have an even number of negative, well then the whole thing is going to be, the whole thing is going to be positive.
Which is an example of an odd number?

Is the number 25 an odd number of factors?
All square numbers have an odd number of factors. For example, the number 25 has three factors: Because 25 is a square number it has an odd number of factors.
Is the number 12 an odd number of factors?
The number 12 has six factors: If 12 is divided by any of the six factors then the answer will be a whole number. Square numbers are formed by multiplying a number by itself.
