    Question Java test questions

    I am having trouble solving these questions that could be on my test in 3 hours:

    1. 5 factorial is the product of 5, 4, 3, 2, 1. 10 factorial is the product of the integers 10 down to 1. Write a program that displays the value of 5 factorial. In the same program compute and display the value of 10 factorial making use of the result you computed for 5 factorial. Be sure to display your results with appropriate labels.

    2. Write a program that computes and displays with an appropriate label the value of
    (5) (6) (7)
    ------------
    (2) (3)

    A forum is not a good place to post a request for urgent help or help with anything that includes a deadline that's closer than 2 or 3 days out. Asking for help with no apparent effort on your part is also a faux pas. For these transgressions, those who might otherwise provide assistance will chuckle and then ignore.

    I am basically asking for a more in-depth explanation of each question. I am not looking for coding, I frankly just don't understand what each question is truly looking for.

    You should have said, though time-critical topics are still often ignored.

    What don't you understand? The first is straightforward to me but may not be to you, so explaining what you don't understand would be helpful.

    The meaning of the second might be obscured by the limitations of this medium. Why are the numerals in parentheses? Is that supposed to be ( 5 * 6 * 7 ) / ( 2 * 3 ) ?

    Number 1 looks like a good candidate for recursion, since it involves factorials. But you can probably do it with a for loop that counts down. In a nutshell, the question is asking: "If given the number 5, write a program that calculates 5*4*3*2*1."

    Number 2 looks weird, like it just wants a quick program that does division of 2 sets of numbers. I'd ask my teacher for clarification if I were in your shoes.

    Honestly, I do not know factorials, but I am going into class early to learn a little before the test.

    The parentheses through me off as well, I am wonder the same as you about the multiplication.
