A museum wishes to display six paintings next to one another on a wall. In how many ways may this be done?

6!

Step-by-step explanation:

in these types of questions you take the highest number which in this case is 6 and multiply it by the numbers smaller than it.

and not to make it longer you say 6! in the calculator and you get the answer

Hope this helped :)
