Is there a software that simplify mathematical expressions?

    When I work with circuits that contains some capacitors, inductors and resistors and the supply is AC, I get long mathematical expressions and I have to do many calculations and many steps.
    I would like to use an online website or a free software that is able to simplify these expressions. I need the software to support complex numbers or square root of (-1).

    To clarify what I need, Here is a quick example:
    I need the software to expand this expression (R1 - i * Xc) * (R2 + R3) to this expression
    R1*R2 + R1*R3 - i*Xc*R2 - i*Xc*R3

    Also, It is better if the software supports ratios.

    I would be grateful if you give me a link or a software,
    Thank you very much,

    Will do it. You cannot have variables with two characters so change R1, R2 and R3 to a, b and c. Xc to x.

    Just plug formula into search bar and it will solve for you.

    These things can be done easily in Mathematica or Maple.

    Mathematica is made by Wolfram Research - same guy that offers - for free (handle all this simple stuff).

    Whoever put together the Wolfram Alpha web site was one bright individual. That site amazes me every time I use it.
