Product of three negative integers is a negative integer
Solution:
The given statement is: Product of three negative integers is a negative integer. To prove whether this statement is true or false let us substitute the value of a, b, and c in a × b × c = abc.
Let us consider a = -4, b = -3, c = -2.
On substituting the values of a, b, c we have,
-4 × -3 × -2 = -24
In this case the product is a negative integer. Applying integer rule (-) × (+) = -
Therefore, the product of three negative integers is a negative integer
✦ Try This: State whether the statement is true or false. -71 × -90 × -91 gives the product as a positive integer
We can apply integer rules and the multiplication rules to identify whether -71 × -90 × -91 gives the product as a positive integer or not
