You could defer construction of the "correct" tree until the entire
expression is built - construct a stack of operands and operators,
left-to-right, then process it once the entire equation is scanned
and generate the tree at that point.

That means ANTRL will treat all operators as the same level and left
to right, but it does centralizes your precedence table.
