Assume there are approximately 5,000,000,000 (5 billion) people on Earth.
What would you estimate to be the result,
if you multiply together the number of fingers on every person's left-hands?
(For the purposes of this exercise, thumbs count as fingers.)
If you cannot estimate the number then try to guess how long the number would be.
The Answer is 'ZERO'
Some ppl on the earth would have no fingers on the left hand.
So any thing multiplied by 0 is 0.
Hence 0 is the answer.
