Can you find a way to make:
$5\ 5 \ 5 \ 5 = 19$
by adding any operations or symbols? You can use only these symbols:
$+,\ -,\ *,\ !,\ /,\ \hat\, ,\ ()$.
It is limited to this list, and concatenation is also allowed. You cannot add other numbers to the equation.
Answer
Here's one way I found:
$\dfrac{5!-(5\times 5)}{5}=19$
Or, using just the characters explicitly allowed in the question:
(5! - (5 * 5)) / 5 = 19
