      tru, although the most common answer is 1, it's still disputed

            The answer of a calculator will display 1 for 0^0, but if you do some digging, the answer is still disputed,

            Linked below is an awesome read more about the topic, the basic rundown is, if you're looking at it algebraically,
            0^0=1
            But if you're doing stuff with limits,
            0^0 is an indeterminate form

            also, I'm not sure what calculator you're using, but the google calculator and my Casio 115 (As well as my Casio 991) give me 0!=1, and 1! isn't nessicarily 1x1, it's just 1, i believe.

                  like 7! is 7x6x5x4x3x2x1 (you don't need one) is 5040.

                    The thing is, you don't multiply anything in 0!, which is indeed, pretty confusing.
                    You basically look at it from a logical angle instead;
                    How many ways are there to arrange 'nothing'?
                    1.
                    By having nothing.
                    So, taking your example, 7! you now have a number of ways to rearrange 7 things,
                    and 0! would be 1 because there's one way to arrange it.
                    0! is also what's known as an empty product (Here's a wiki article on empty products:
                    https://en.wikipedia.org/wiki/Empty_product)

                      The thing is how to arrange 0 things????? Suppose you have nothing an you want to arrange it. That makes no sense!

                            @legendaryboy991 Think of it this way: How many ways to arrange 0 thins? 1: Do nothing. you can't do anything else 🙂

                            It seems that you have started your math journey pretty early! 😄
