    Postfix/Prefix

    heeelp.
    I've got a test tomorrow on binary / expression trees, and I understand it all except this whole concept of writing expressions in prefix/postfix/infix. My teacher worked through changing the expression a term at a time, but I always seem to get stuck near the end...
    Code:
    6 + (5 + 1) * (3 - 2) ^ 2
    How would I express this in pre/post fix?

    Every passing hour brings the Solar System forty-three thousand miles closer to Globular Cluster M13 in Hercules -- and still there are some misfits who insist that there is no such thing as progress.
