If the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples.
Step 1: To justify
(1) If the product of two whole numbers is zero, then one or both of them will be zero.
Step 2: Justification If the product of $$2$$ whole numbers is zero, then one of them is definitely zero. For example, $$0\times 2=0$$ and $$17\times 0=0.$$
Now, If the product of $$2$$ whole numbers is zero, then both of them may be zero. For example, $$0\times 0=0.$$
However, $$2\times 3=6$$. Since the numbers to be multiplied are not equal to zero, therefore, the result of the product will also be non-zero.
