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
×
2
=
0
and
1
7
×
0
=
0
.
Now, If the product of
2
whole numbers is zero, then both of them may be zero.
For example,
0
×
0
=
0
.
However,
2
×
3
=
6
.
Since the numbers to be multiplied are not equal to zero, therefore, the result of the product will also be non-zero.
