CalculatorHow quickly can you find the answer to:

5  x  4  x  3  x  ...  x  -3  x  -4  x  -5

 [Ref: ZTFI] © Kevin Stone

Answer: Zero.

In full the question is:

   5  x  4  x  3  x  2  x  1  x  0  x  -1  x  -  2  x  -3  x  -4  x  -5

As you can see, there is a x 0 in there, and anything times zero is zero.
