Two questions 1; what does 2n mean? 2:By accident I posted my question as an answer can you tell me a way to delete it. Please make sure that Ms.Sue answers this thank you.

  • math -

    n is your input number
    2 n is twice your input number

  • math -

    So that technically that means that 2n means x2

  • math -

    yes 2 n means n times 2
    same as
    2(n)
    or
    2 * n
    or
    2 x n
