Multiplication of Three or more negative integers

Multiplication (Two Positive Integers) Multiplication (Two Negative Integers) Multipication (Positive and Negative Integer) Multiplication of Three or more negative integers

In a multiplication expression, if the number of negative integers is even, then the resultant integers will always be positive integers. And if the number of negative integers is odd, then the resultant integers will always be negative integers.

Let's try following example and understand this better

Example 1 = (-2) X (-2)
Answer = 4


Example 2 = (-2) X (-3) X (-1)
Answer = (-6)


Example 3 = (-2) X (-5) X (-3) X (-1)
Answer = 15


Example 4 = (-2) X (-2) X (-2) X (-2) X (-2)
Answer = (-32)

So from the above you can see that in example-1 & example-3 number of negative integers is even i.e. two & four and hence their product is also a positive integers i.e. 4 & 15.

And example-2 & example-4 number of negative integers is odd i.e. three & five and hence their product is also a negative integers i.e. (-6) & (-32).
