Answer:
To find the factorial of a number, multiply all of the positive integers equal to or less than that number. For example, 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5,040. To calculate permutations, we use the equation nPr, where n is the total number of choices and r is the amount of items being selected.
