Simple Calculator

Tips for using a simple calculator effectively:

• Order of operations: Remember that multiplication and division are performed before addition and subtraction.
• Percentage calculations: To calculate a percentage (e.g., 15% of 200), enter 200 × 15 ÷ 100, or use the percentage button if available.
• Chain calculations: You can chain multiple operations together, and the calculator will evaluate them in the correct order.
• Negative numbers: Use the +/- button to change the sign of a number.
• Decimal precision: Be aware of rounding in calculations involving many decimal places.
