The empty product on numbers and most algebraic structures has the value of 1 (the identity element of multiplication), just like the empty sum has the value of 0 (the identity element of addition). However, the concept of the empty product is more general, and requires special treatment in logic, set theory, computer programming and category ...
The amazon website searches for the most rated, highly demanded, frequently bought and most wished for products which are then sold in the new amazon store under separate categories. Along with the paper price tags, the online-review cards will also be available for the customers to read before buying the product. [126] [127]

In short, one should make distinction between expressions and there values, and an empty product is an expression.
