The two non-zero numbers, whose product is zero are:

Any number let's say X and "Y/∞" would be = XY/∞ =0

The two non-zero numbers, whose sum is zero are:

X/∞ and Y/∞ =0+0 =0

PRODUCT

I don't think there are2 non-zero numbers whose product is0. Here's why:

 

If we have a × b =0, then either a =0 or b =0 or both equal0.

 

SUM

2 non-zero numbers can have a sum of zero. Let us illustrate this with2 numbers: a and b.

 

If a + b =0, then either (a = -b) or (b = -a).
