Many students forget the correct order (PEMDAS/BODMAS) leading to incorrect calculations. Double-check each step and use parentheses to group operations.
Always check your calculator is in the correct mode (degrees or radians for trigonometry) before starting a problem. Reset the calculator if unsure.
Forgetting to use parentheses when squaring a negative number (e.g., (-3)^2 vs. -3^2) will give you the wrong answer.
For complex equations, break them down into smaller steps, writing down intermediate results to avoid input errors. Use the calculators memory function if needed.
Not using the fraction button correctly or converting decimals prematurely can lead to rounding errors. Use the fraction function for exact answers.
Encourage practicing mental math and estimation skills to develop a better understanding of the concepts and reduce reliance on the calculator for simple calculations.
