    Default Convert string operation symbols "+", "-", "/", "*" etc.

    What is the easiest way to convert a string expression to something I can solve? I have never used association lists but could that work? Or maybe the replaceAll() function?

    For clarification I'm trying to solve functions such as "3 + 4", or [ "3", "+", "4"].

    I once wrote a blog article for this forum: the article develops a compiler for infix expressions and shows you a way how to parse and interpret/evaluate those expressions. The blog article contains all the code. If I'm not mistaken there's a link to my blobs on the right side of this reply.

    kind regards,

    Jos

    Surely "blogs"?
    I'm not sure showing off your blobs on a public forum is entirely legal...
    Please do not ask for code as refusal often offends.
