A little difference

Determine the value of the expression below: (6!+5!)×(4!+3!)×(2!+1!)(6!5!)×(4!3!)×(2!1!). \frac{(6! + 5!) \times (4! + 3!) \times (2! + 1!)}{(6! - 5!) \times (4! - 3!) \times (2! - 1!)}.

Note: The "!!" symbol is the factorial operation, but there's a clever shortcut for solving this that entirely avoids multiplying out the factorials!
