Question

If the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples.

Answer 1

If the product of 2 whole numbers is zero, then one of them is definitely zero.

For example, 0 × 2 = 0 and 17 × 0 = 0

If the product of 2 whole numbers is zero, then both of them may be zero.

0 × 0 = 0

However, 2 × 3 = 6

(Since numbers to be multiplied are not equal to zero, the result of the product will also be non-zero.)
