    Exclamation calculator problem

    So my calculator and I are at war on this last problem of my online homework, and I'm trying to get it to solve a present value equation, though, it keeps telling me "OVERFLOW Error"...

    Here is the Problem:



    Here's what I put in my calculator:
    2000(1+(.04/365)^-365(3.5)

    Dont take this the wrong way, but are you sure you put your brackets in the correct position?
    2000 * ( 1 + (0.04/365) )^(-365*3.5)
    As opposed to what I read being
    2000 * (1 + (0.04/365) ^(-365*3*5) )

    Hello, Lariat!

    You're probably entering the problem incorrectly.
    . . The calculator is trying to find the answer you asked for . . .


    Here's what I put in my calculator: .2000(1+(.04/365)^-365(3.5)
    . .
    You're missing some parentheses.

    This is what you entered: . 2000 \times \bigg(1 + \left(\tfrac{0.04}{365}\right)^{-365} \times 3.5

    Your approach is correct, your execution is wrong.


    We want: . 2000\left(1 + \tfrac{0.04}{365}\right)^{[-365(3.5)]}


    If you simply must do it all in one string of operations,

    . . enter: . 2000\;\boxed{\times}\;\boxed{(}\;1\;\boxed{+}\;0.0  4\;\boxed{\div}\;365\;\boxed{)}\;\boxed{\wedge}\;\  boxed{(}\;\boxed{(-)}\;365\;\boxed{\times}\;3.5\;\boxed{)}
