Tips for Best Results

• • Always check if you're in the correct angle mode (degrees vs radians)
• • Use parentheses for complex expressions to ensure correct order of operations
• • For very large factorials (n! where n > 170), consider using logarithmic approximations
• • Memory functions are perfect for multi-step calculations requiring intermediate results
• • Review your history regularly to catch and correct any input errors
