. Product of three negative integers is a negative integer
The stated statement is: A negative integer is the product of three negative integers.
Substitute the values of a,b, and c in a ,b ,c =abc to see if this assertion is true or false.
Let the numbers a= - 4, b= - 3 and c= -2.
We get - 4× , -3×, -2 =24 by swapping the values of a,b,and c.
The product is a negative integer in this example.
Using the (−) × (+) = − integer rule
As a result, the sum of three negative integers is also negative.
Hence, the correct option is (a) i.e. True.
