Issue: Methods need explicit lifetime annotations for borrowed data.

Fix Required:

// Should be:
fn binary_op_to_asciimath<'a>(&self, op: &'a BinaryOp) -> &'a str

2. Missing Type Imports

Locations: Multiple modules Issue: Types used but not imported into scope

3. Type Mismatches

Error Type: E0308 (mismatched types) Issue: Type inference or explicit type declarations needed
