Common Mistakes to Avoid
1. Order of Operations Errors
Remember PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction):
- Use parentheses to group operations when needed
- Be careful with implied multiplication (e.g., 2πr vs. 2×π×r)
- Check your calculation history if results seem unexpected
2. Fraction Input Errors
- Always enter the numerator before the denominator
- Use the fraction key (□) between numerator and denominator
- Double-check mixed number entries
3. Mode Settings
- Ensure you’re in the correct mode (degrees vs. radians for trigonometry)
- Check if you’re in float or fixed decimal mode when needed
- Verify statistical settings before entering data
