Maths Product
From Mycoted
What is the product (ie. Multiplying all the numbers together) of the following series: (xa),(xb),(xc),.....(xz)?
(A bit harder but really nothing for maths oriented minds)
Answer  

Zero (0). Reasoning: any number or series of numbers multiplied by zero will equal zero. The factor (x  x) = 0 See, we told you it was really nothing.
