What is a factorial?
Can you explain what a factorial is?
Sure thing! A factorial is a mathematical function represented by an exclamation mark (!). It denotes the product of all positive integers up to and including a given integer. For example, 5! (read as "5 factorial") is equal to 5 x 4 x 3 x 2 x 1, which equals 120.
