# Simplified example of expression parsing
def parse_expression(tokens):
    expression_tree = ExpressionTree()
    for token in tokens:
        if token.is_number():
            expression_tree.add_number_node(token.value)
        elif token.is_operator():
            expression_tree.add_operator_node(token.value)
        # Handle additional token types
    return expression_tree

Recent advancements in this field have improved accuracy from 91% in 2023 to 96.5% in 2025, even for complex expressions involving multiple levels of fractions, exponents, and specialized notation.

Problem-Solving Algorithms
