How did you construct the grammar?

I'm using JavaCC to parse expressions and generate a parse tree (not using JJTree,) and I've ran into a problem. JavaCC grabs the expresions from right-to-left, but I need to grab them left-to-right.<br />
<br />
For example this expression:<br />
<br />
5+2-3-1<br />
<br />
This should be 3. However it wil end up being 5:<br />
<br />
(3-1) = 2<br />
(2-2) = 0<br />
5 + 0 = 5<br />
<br />
I want to reverse this process.. What can I do? I've constructed a very simple parse tree, do I need to iterate over the tree in a different order?

JavaCC expression parsing

Programming theory deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features, along with introductory programming concepts like program structure, variable declaration and conditional and looping constructs. Sub-disciplines include the formal semantics of programming languages, type theory, program analysis and transformation, comparative programming language analysis, metaprogramming, domain-specific languages, compiler construction and run-time systems.
