Product of two negative integers is a negative integer
Solution:
The given statement is: Product of two negative integers is a negative integer. To prove whether this statement is true or false let us substitute the value of a and b in a × b = ab.
Let us consider a = -4, b = -3.
On substituting the values of a and b in a × b we have,
-4 × -3 = 12
In this case the product is a negative integer. Applying integer rule (-) × (-) = +
Therefore, the product of two negative integers is a positive integer. Hence the given statement is false.
✦ Try This: State whether the statement is true or false. -71 × -90 gives the product as a positive integer
We can apply integer rules and the multiplication rules to identify whether -71 × -90 gives the product as a positive integer or not
